Understanding the migration process: what it means to move legacy systems to the cloud

We describe the practical steps that convert entrenched systems and software into maintainable, scalable services.

What is a legacy application and legacy system migration?

A legacy application is aging on-premises software or hardware that remains essential despite compatibility gaps with modern tools.

The migration process moves those applications and their data into a modern environment while preserving business logic and records.

Common examples and why they’re still critical to business

Typical footprints include COBOL mainframe apps, on-prem ERP like SAP R/3 or early Oracle E-Business Suite, and older CRM platforms such as Siebel.

These systems endure because they run core workflows, hold years of transactional data, and feed downstream services, so continuity matters.

Footprint	Challenge	Modern solution
Mainframes (COBOL)	Monolithic code, scarce skills	Container wrap or refactor, managed services
On‑prem ERP/CRM	Tight integrations, hardware dependence	Replatform, APIs, elastic compute
Line‑of‑business apps	Outdated interfaces, brittle integrations	Refactor, interface layers, integration platforms

• We balance rehost, replatform, refactor, and replace paths based on risk and value.
• We focus on data fidelity and business continuity during every cutover.
• We use managed services and elastic compute where they reduce hardware and maintenance burden.

Why migrate now: business value, performance, and risk reduction

We help organizations capture measurable business value by modernizing critical systems with clear cost, performance, and risk targets. Acting now reduces waste, improves responsiveness, and sets a predictable path for compliance and security.

Benefits: cost savings, scalability, security, and agility

Pay-as-you-go economics and autoscaling eliminate over‑purchasing hardware and data center spend, lowering operating costs while letting teams focus on innovation.

Performance gains show up as faster throughput and lower latency, meeting user expectations for always‑on services.

Managed identity, encryption, and continuous patching improve security posture compared with aging on‑prem controls.

The risks of sticking with old systems

Inaction raises maintenance burden, creates brittle integrations, and limits scalability. Dependence on scarce subject matter experts increases operational risk and cost over time.

When to modernize vs. replace

Decision factor	Modernize	Replace
Business fit	Retain core logic, improve interfaces	New features, faster ROI
Compliance & security	Update controls, phased work	Built‑for‑compliance platforms
Team & skills	Augment training, partner support	Outsource or repurchase

We quantify value drivers and recommend selective lift tactics for quick wins, while mapping training and change plans to minimize disruption. For a concise overview of benefits, see our resource on benefits of cloud migration.

Align search intent and goals: turning informational research into an actionable migration plan

We translate discovery and stakeholder intent into an actionable roadmap that links technical workstreams with clear business targets. Establishing why you move—scalability, reliability, or security—drives the chosen strategy and the measurable outcomes we track.

Defining success metrics: cost, uptime, performance, and user satisfaction

We set KPIs and SLAs that map technical signals to business value. Examples include latency and error rates tied to conversion, uptime tied to revenue impact, and NPS tied to user experience.

Mapping intent to steps: from assessment to ongoing optimization

We document a time‑bound plan with checkpoints and owners for each step of the process. That plan clarifies assessment, pilots, cutover, and ongoing tuning so executives see progress and risk is contained.

• Translate research into measurable objectives for cost, uptime, performance, and users.
• Define data quality goals so datasets are validated, usable, and auditable.
• Align teams across IT, security, and business with clear decision rights and escalation paths.
• Commit to post‑go‑live reviews and continuous improvement to sustain gains.

Start with discovery: SWOT, assessment, and environment audit

We begin discovery with targeted audits and stakeholder interviews that reveal technical debt, hidden integrations, and operational constraints.

Conducting a focused SWOT

We run a living SWOT that evolves with the project, exposing constraints early and informing risk mitigation across schedules and budgets.

This living record captures strengths, weaknesses, opportunities, and threats so teams can adapt plans as systems and risks change.

Application and dependency mapping

We inventory applications, interfaces, datasets, and schedules, producing a dependency map that de‑risks sequencing and reduces unexpected breakages.

Skills and resources assessment

We benchmark capacity, network architecture, and performance baselines to size target environments and set realistic goals.

We evaluate team skills and resources, identifying training needs and partner requirements before execution begins.

Focus	What we check	Outcome
SWOT	Business fit, technical debt, external risks	Prioritized risk register and mitigation plan
Dependency Map	Apps, APIs, data flows, schedules	Sequenced cutover plan, fewer integration failures
Capacity & Resilience	Performance baselines, recovery SLAs	Right‑sized targets and continuity requirements
Skills & Compliance	Team gaps, training, data protection rules	Staff plan and partner scope, compliant design

• We prioritize quick wins with low complexity and high value to build momentum.

Choose your strategy and roadmap: 6Rs/7Rs for cloud migration

Our roadmap matches business priorities with technical risk, delivering wins fast while protecting critical services.

We apply the 6Rs (Replace/Retire, Retain, Rehost, Replatform, Refactor, Repurchase) and add Extend via APIs for the 7th option. Each path aligns with different costs and benefits, and we map treatments to business value and complexity.

Rehost, or a lift shift, accelerates timelines and reduces cutover time. Replatform adds targeted optimizations for performance and cost without a full rewrite.

Strategy	When to use	Key benefit
Rehost (lift shift)	Low change tolerance, fast schedule	Speed, minimal refactor
Replatform	Need quick gains plus cost/perf tweaks	Better efficiency, moderate effort
Refactor / Re‑architect / Rebuild	Long‑term scale and maintainability	Performance, agility, lower tech debt
Replace / Repurchase / Retain / Extend	Commodity functions or wrapped legacy apps	Faster ROI or incremental modernization

We sequence work by value, complexity, and dependencies. That creates a pragmatic plan with milestones, sized resources, realistic time estimates, and contingency budgets.

Risk controls include rollback paths, data protection, and portability measures—containers and portable architectures reduce vendor lock‑in and future switching costs.

Select the right cloud type and vendor for your legacy systems

We help you choose an environment that fits each application’s performance, compliance, and cost needs. Public providers like Azure offer cost‑effective scalability and managed services for high‑variance workloads. Private platforms give stronger control where regulations or data residency demand strict oversight.

Hybrid blends both for sensitive systems that must remain on‑prem while benefiting from public elasticity. Multi‑cloud lets you use best‑of‑breed services across vendors, balancing risk and regional presence.

Avoid vendor lock-in with portable architectures

We design for portability using containers, microservices, and open standards so systems remain moveable and modular. This lowers switching costs and reduces long‑term dependency risks.

• Align workloads with public, private, hybrid, or multi‑cloud models for performance and cost.
• Evaluate vendors on service breadth, regional presence, and integration with your platform and toolchain.
• Plan landing zones, network connectivity, and governance scaffolding for consistent operations.

Compliance and security considerations in the United States

We embed HIPAA, GDPR, and SOC controls into architecture, identity, and data residency decisions from day one. Cloud providers offer built‑in tools and continuous updates that help meet these standards, but roles and audits remain a shared responsibility.

Requirement	When to choose	Design focus	Typical controls
Cost & Scalability	Variable demand, public services	Autoscaling, managed services	Billing alerts, right‑sizing
Regulatory Control	Protected health or resident data	Private or hybrid with strict residency	Encryption, segmented networks, audits
Resilience & Latency	High‑availability systems	Multi‑region or multi‑cloud deployments	Replicated data, failover testing
Portability	Long‑term flexibility needs	Containerized apps, service meshes	Open APIs, CI/CD pipelines

Access controls and segmentation protect sensitive data while enabling secure collaboration. We clarify shared responsibility with providers and define audits, backups, and incident response in the architecture so teams can operate confidently and compliantly.

De-risk execution: pilot migrations, testing, and parallel runs

We reduce uncertainty by validating the plan in controlled pilots before a broad rollout. A pilot proves the migration process with measurable goals, limiting exposure while the team refines scripts, tooling, and runbooks.

Designing a pilot: scope, test data, and success criteria

Scope pilots for representative workloads and datasets, with clear success criteria tied to performance, accuracy, and user experience.

Create production‑like test data and environments so integrations and scale issues surface early, not during the main cutover.

User acceptance, performance testing, and monitoring setup

Formalize UAT with real users, and run targeted performance testing while instrumenting metrics and logs.

Configure monitoring and alerts during the pilot so anomalies trigger clear actions and reduce mean time to resolution.

Parallel runs and rollback procedures

Where feasible, run old and new systems in parallel, synchronizing data paths to enable a controlled switchover.

Document and rehearse rollback steps so the team can restore service quickly if acceptance criteria fail.

• Iterate: deploy, validate, expand—lessons compound into safer, faster migrations.

legacy to cloud migration: data, applications, cutover, and downtime control

We protect business continuity by treating data movement, deployments, and cutovers as coordinated engineering efforts with measurable checkpoints.

Data migration and integrity: mapping, ETL pipelines, and validation

Accurate data movement is the foundation of a safe shift. We engineer ETL pipelines that map, cleanse, and transform schemas, then reconcile records to prevent loss.

Validation runs at record level, with automated checks and manual spot audits to confirm parity before any cutover.

Application deployment paths: VMs, containers, and platform services

We select deployment targets based on application behavior: VMs for parity and legacy runtime needs, containers for portability, or managed PaaS for reduced ops overhead.

Deployment templates and CI/CD reduce human error and let us repeat proven steps across systems.

Cutover strategies: incremental moves, canary releases, and scheduled maintenance windows

Cutover playbooks use incremental moves and canary releases to limit blast radius and surface issues early.

We coordinate scheduled maintenance windows with stakeholders, run parallel operations where feasible, and use services like Azure Site Recovery and regional diversification to keep RTO/RPO within agreed thresholds.

• We test end‑to‑end flows before and after cutover, validating performance, logging, and error handling.
• We communicate timelines and expected brief downtime to users and business owners.

Optimize after go-live: monitoring, cost control, and continuous improvement

Once the cutover completes, we move from delivery into steady operational improvement, aligning observability, cost discipline, and security with business goals.

Observability and tuning are first priorities. We deploy full‑stack telemetry that tracks latency, errors, and saturation so teams tune performance across environments.

Cost and resource control follows. We rightsize compute and storage, enable autoscaling, and apply policy guards that prevent spend drift while preserving service levels.

• We validate security posture for identity, encryption, and patching against compliance requirements.
• We run a post‑migration audit that confirms data completeness, KPI attainment, and lessons learned.
• We decommission legacy hardware and redundant licenses in a controlled, auditable process.

Governance and feedback close the loop. We set change controls, tagging, and cost centers so new workloads follow standards, and we gather user feedback plus telemetry for iterative improvements.

Focus area	Activity	Outcome
Observability	Full‑stack metrics, traces, logs	Faster root cause resolution, better performance
Cost Management	Rightsizing, autoscaling, policy enforcement	Predictable spend, optimized resources
Security & Audit	Post‑go‑live reviews, patching, audits	Closed gaps, compliant posture
Decommissioning	Hardware retirement, license rationalization	Lower maintenance overhead, reduced attack surface

Tools and platforms that simplify the migration process

A focused toolset reduces custom code and speeds integration between on‑prem systems and modern platforms. We choose solutions that let teams move functionality and data with predictable risk and measurable outcomes.

iPaaS, ETL, and API gateways: connecting legacy systems and modern platforms

We use integration platforms and ETL as the plumbing that keeps systems talking while work proceeds. iPaaS tools like MuleSoft and Boomi sync data and expose functions as APIs, reducing bespoke adapters.

ETL platforms—Informatica, Talend, and Azure Data Factory—handle bulk transfers, schema evolution, and ongoing sync without lengthy rewrites. API gateways such as Kong, Apigee, and AWS API Gateway secure services, apply rate limits, and provide analytics.

Low-code and automation for extending applications and building UIs

Low‑code platforms like Superblocks let teams build internal UIs and automations on top of existing databases, wrapping systems via REST APIs and shortening delivery cycles while preserving governance.

Governance, access, and testing tools for secure, compliant transitions

We design RBAC, SSO, and audit logging into every project, and instrument observability from day one with Datadog, New Relic, or Splunk. CI/CD gates include security scans and automated tests so velocity and safety move together.

Tool Type	Examples	Primary Role	Benefit
iPaaS	MuleSoft, Boomi	Integration & API exposure	Fewer custom adapters, faster integrations
ETL / Data Pipelines	Informatica, Talend, ADF	Bulk move & transform data	Reliable transfers, schema handling
API Gateway	Kong, Apigee, AWS API Gateway	Security & traffic control	Standardized auth, analytics
Observability & Governance	Datadog, New Relic, Splunk	Monitoring & audit	Operational clarity, compliance evidence

• We bridge on‑prem and cloud platforms with iPaaS, limiting bespoke code.
• We centralize testing and CI/CD quality gates to keep releases safe.
• We combine RBAC and SSO so teams get access while controls stay strict.

Common pitfalls and how to avoid them in cloud migrations

Practical plans fail less often when teams spot hidden costs and set realistic expectations up front.

Underestimating total cost and over-relying on a pure lift shift is a frequent issue. Organizations often budget for a simple system move, then face license charges, third‑party fees, and higher run costs as traffic grows.

We expose hidden cost drivers early, quantify long‑term fees, and recommend targeted changes so a lift recovers value without adding technical debt.

Staff, analysis, and change fatigue

Relying on inexperienced teams creates risks and lost time. We staff projects with seasoned engineers and partners who have executed migrations at scale.

We balance analysis: time‑boxed discovery prevents paralysis while iterative delivery reduces rework and keeps momentum.

Change fatigue is a real problem. We mitigate it with clear communication, phased rollouts, and focused training so users adopt new systems with confidence.

• We map cost drivers—licenses, integrations, scaling—so budgets hold.
• We limit pure lift where it creates debt, adding optimizations that improve performance and cost.
• We staff appropriately and use partners to fill gaps in experience.
• We use contingency checkpoints and failover tooling—region redundancy and Azure Site Recovery—to reduce downtime and data loss risks.

Our plan keeps work actionable: checkpoints, rollback paths, and training ensure the team moves forward without surprising the business.

Conclusion

We conclude with a focused path that turns discovery into action and measurable outcomes. A clear migration plan, built from pilots and staged cutovers, reduces risk while preserving service continuity.

Post‑go‑live audits verify data integrity, confirm security and compliance, and ensure KPIs meet targets; retiring legacy components after stabilization lowers overhead and operational risk.

We summarize: structured steps convert intent into business value; choose modernize versus replace based on compliance, talent, and total cost; pilots and testing limit exposure; ongoing governance sustains cost, performance, and security gains.

We partner with your team, across assessment, strategy, execution, and optimization, and we invite stakeholders to prioritize the next wave by ROI, using lessons learned to accelerate subsequent cloud migration.

FAQ

What does it mean to move legacy systems to the cloud?

Moving older applications and hardware platforms into a modern platform means rehosting, replatforming, refactoring, or replacing those systems so data, services, and users run on scalable infrastructure rather than aging on-premises servers. We assess applications, dependencies, and data flows, then create a migration plan that balances cost, performance, and security to reduce operational burden and speed delivery.

What is a legacy application and why is migration complex?

A legacy application often uses outdated languages, tightly coupled architectures, or bespoke hardware that makes updates, scaling, and security harder. Complexity arises from interdependencies, data mapping, regulatory controls, and the need to preserve uptime for users while minimizing risk during cutover.

What business benefits can we achieve by modernizing old systems now?

Modernization delivers lower total cost of ownership through rightsizing and automation, improved performance with autoscaling, stronger security posture and compliance, and faster time to market thanks to containerization, microservices, and API-led integration that enable agility and operational efficiency.

What are the risks of keeping old systems in place?

Maintaining aged hardware and unsupported software increases maintenance costs, creates single points of failure, widens talent gaps as skills become scarce, and raises security and compliance exposure, which together heighten business risk and slow innovation.

How do we decide whether to modernize, replace, or retain an application?

We map business value, technical debt, compliance needs, and cost to choose a fit-for-purpose strategy: rehost for quick lift-and-shift, replatform for incremental optimization, refactor or rebuild for strategic capabilities, or replace when a SaaS solution offers better long-term value. Prioritization comes from ROI, risk, and user impact.

How do we define success metrics for a migration program?

Success metrics include cost targets, uptime and performance SLAs, data integrity measures, and user satisfaction scores. We set baselines during discovery, then track observability, incident rates, and spend management to validate results and guide continuous improvement.

What does a discovery phase cover and why is a SWOT useful?

Discovery includes environment audits, application and dependency mapping, data inventories, and skills assessments. A SWOT surfaces strengths, weaknesses, opportunities, and threats so stakeholders can prioritize workloads, estimate timelines and budget, and decide if training or partner support is required.

What are the 6Rs/7Rs strategies and when do we apply them?

The common options are Rehost (lift and shift), Replatform, Refactor, Rearchitect, Rebuild, Replace/Repurchase, and Retain/Extend. We align each option with business goals: quick cost relief via rehosting, efficiency gains via replatforming, and long-term scalability via refactoring or rebuilding, using APIs and the strangler pattern when incremental change is preferred.

How do we select the right cloud type and provider for our workloads?

Selection depends on workload sensitivity, performance needs, compliance requirements, and cost constraints. Public, private, hybrid, or multi-cloud designs map to different security, latency, and governance needs. We evaluate vendors on portability, managed services, tooling, and data residency to avoid vendor lock-in.

How can we avoid vendor lock-in during migration?

Favor portable architectures—containers, microservices, and standardized APIs—use open-source tools when viable, and design CI/CD pipelines and infrastructure as code that abstract provider specifics so workloads can move between environments with minimal rework.

What compliance and security standards should U.S. businesses consider?

Important frameworks include HIPAA for healthcare, SOC 2 for service providers, and privacy rules aligned with GDPR where applicable. We implement identity and access governance, encryption, logging, and continuous monitoring to meet regulatory and contractual obligations.

How do pilot migrations and parallel runs reduce execution risk?

Pilots validate scope, test data flows, and confirm success criteria at low risk, while parallel runs let teams operate old and new systems concurrently to verify performance and enable safe rollback. Together these steps reduce downtime, service disruption, and cutover surprises.

What testing should we perform before cutover?

Perform unit, integration, performance, and user acceptance testing, plus data validation and end-to-end observability checks. Load and failover tests validate autoscaling and resilience, while security scans and compliance checks ensure posture readiness.

How do we manage data migration and ensure integrity?

We map source schemas, design ETL pipelines with checkpoints, and run reconciliation and validation routines. Incremental syncs and canary releases minimize data drift, and detailed rollback plans protect against corruption during cutover.

What cutover strategies limit downtime and user impact?

Options include incremental migration, blue/green deployments, canary releases, and scheduled maintenance windows for heavier moves. We choose the approach that balances user experience with technical constraints, often combining strategies to reduce risk.

How do we control costs after go-live?

Implement rightsizing, autoscaling policies, tagging for cost allocation, and continuous spend monitoring. Regular audits and governance guardrails prevent overruns and ensure resource efficiency aligned with business priorities.

What post-migration activities are essential?

Observability tuning, performance optimization, security hardening, decommissioning old hardware, knowledge transfer, and ongoing optimization cycles keep the environment efficient, secure, and aligned with evolving business needs.

Which tools accelerate integrating old systems with modern platforms?

Integration platforms (iPaaS), ETL tools, API gateways, and CI/CD pipelines simplify connectivity and automation, while low-code platforms enable rapid UI extension. Governance and testing tools maintain access control and compliance during transition.

What common pitfalls should we avoid in migration projects?

Avoid underestimating total cost, over-relying on lift-and-shift without optimization, and staffing projects with inexperienced teams. Balance analysis and action to prevent change fatigue, and ensure clear stakeholder alignment to maintain momentum.
