What's Included
Database Replatforming
Migration from self-managed databases on EC2/VMs to managed services: RDS, Aurora, Azure SQL Managed Instance, Cloud SQL. Automated backups, patching, failover, and monitoring handled by the cloud provider.
Application Replatforming
IIS on Windows VM → Azure App Service (the deployment slot model handles staging-to-prod cutover natively). Java on Tomcat → AWS Elastic Beanstalk or Cloud Run. .NET Framework 4.x staying on Windows → Azure App Service Windows tier; .NET 6/8 ready to leave Windows → Linux containers on ECS or App Service Linux. We containerise where it earns its keep, not as a default.
Messaging & Cache Replatforming
Migration from self-managed RabbitMQ, Kafka, Redis, and Memcached to managed equivalents: Amazon MQ, MSK, ElastiCache, Azure Cache for Redis, and Memorystore.
Storage Replatforming
File server migration to S3, Azure Blob, or GCS with appropriate access patterns, lifecycle policies, and integration with existing applications — eliminating self-managed NAS/SAN in Indian data centres.
Replatform Assessment
Workload-by-workload analysis identifying replatform candidates, estimating effort, projecting operational savings, and prioritising based on risk and ROI for Indian enterprise portfolios.
Post-Replatform Optimisation
Configuration tuning for managed services, auto-scaling policy setup, Reserved Instance planning, and operational runbook updates reflecting the new PaaS-based architecture.

Replatform Is the 80/30 Path — 80% of Cloud Benefits at 30% of Refactor Cost
Replatform cloud migration is the answer when rehost is too cheap and refactor is too expensive. Lift-and-shift moved your VMs to AWS Mumbai, but they still need patching, backup tuning, and OS-level monitoring — same toil, different cloud. Refactoring fixes that, but a 6-month microservices rewrite for an internal HR app earns nobody a promotion. Replatform sits between: the same Java app, but on Elastic Beanstalk instead of self-managed Tomcat; the same PostgreSQL database, but on RDS instead of EC2; the same IIS app, but on Azure App Service instead of a Windows VM. Code untouched, operational burden gone. Opsio's replatform migration services move your workloads from IaaS to PaaS: self-managed databases to RDS, Aurora, or Azure SQL; standalone applications to ECS, EKS, or App Service; self-managed messaging to managed Kafka or SQS; and file servers to S3 or Azure Blob. Each migration is carefully planned to require minimal application code changes while delivering maximum operational benefit.
For Indian enterprises, replatforming delivers immediate ROI: 40% reduction in operational overhead, elimination of patching and backup management, auto-scaling for festive-season traffic, and improved reliability through cloud-provider SLAs — all achievable within weeks rather than the months required for full refactoring.
Where does replatform fit in the 6Rs (or 7Rs) of cloud migration? AWS's framework lists Rehost (lift-and-shift, no change), Replatform (lift-tinker-shift, targeted change), Repurchase (move to SaaS, e.g. on-prem CRM → Salesforce), Refactor (full rewrite for cloud-native), Retire (kill it), Retain (leave on-prem), and Relocate (VMware to VMware Cloud). Replatform is uniquely the option that delivers managed-service benefits without forcing a code-level rewrite — and it's the right choice for the 60-70% of typical Indian application portfolios where the business logic is fine but the operational layer underneath isn't paying its rent. Repurchase is right for commodity workflows; refactor is right for differentiating products. Replatform handles everything in between.

Replatform Cloud Migration India — FAQ
What is replatform cloud migration?
Replatform cloud migration (also called lift-tinker-shift) moves workloads to cloud-managed services with minimal code changes. Concrete examples: a self-managed PostgreSQL on EC2 → Amazon RDS, an IIS website on a Windows VM → Azure App Service, a self-hosted RabbitMQ cluster → Amazon MQ, a Java app on Tomcat → AWS Elastic Beanstalk. Application code stays the same; what changes is the runtime your DevOps team has to operate. The cloud provider takes over patching, backup, failover, and scaling — your team gets out of the operations business and back to building features.
How much does replatforming cost in India?
Per-workload pricing typically runs ₹5,00,000-₹15,00,000 in India. Database replatforming (PostgreSQL/MySQL/SQL Server → RDS/Cloud SQL/Azure SQL) sits at the lower band — schema is intact, change is mostly configuration. Application containerisation (VM-based Java/Node/.NET → ECS/EKS/App Service) sits at the upper band — Dockerfile creation, build pipeline, secrets and config externalisation, plus the load-testing pass before cutover. Portfolio pricing applies at 10+ workloads. GST-compliant invoicing throughout.
How long does replatforming take?
Individual workload: 2-6 weeks depending on complexity. A portfolio of 20 workloads: 3-4 months in parallel waves, each wave grouping workloads of similar type (databases together, IIS apps together, messaging together) so the team can reuse the runbook within the wave. We schedule waves around obvious freeze windows — quarter-end for BFSI, festive-season for retail, March 25-31 IST for FY-end batches. Each wave ends with a 1-week stabilisation period before the next starts.
Is replatforming less risky than refactoring?
Yes, significantly. Refactoring rewrites application code; replatforming changes the runtime underneath unchanged code. The blast radius is therefore narrower: a refactor can fail because of a missed business rule buried in 50,000 lines of legacy logic, but a replatform can only fail in the runtime/config/integration layer — which is testable in staging in days, not months. The trade: replatform doesn't unlock cloud-native architectural benefits (event-driven, serverless, microservices). For workloads where current architecture is fine but operations are too expensive, that's the right trade.
Which workloads are best suited for replatforming?
Top replatform candidates by signal: (1) self-managed databases your team patches manually → RDS / Aurora / Azure SQL Managed Instance / Cloud SQL; (2) IIS or Apache web apps on VMs → Azure App Service or AWS Elastic Beanstalk; (3) self-hosted RabbitMQ, Kafka, ActiveMQ → Amazon MQ, MSK, or Azure Service Bus; (4) self-managed Redis or Memcached → ElastiCache or Memorystore; (5) NAS file shares with simple read/write patterns → S3 or Azure Blob with prefix-based access. Workloads that should NOT replatform: anything you'd need to retire, anything already on a SaaS replacement path, and anything with hard kernel-level dependencies (custom drivers, exotic networking).
What is the difference between replatforming and rehosting for Indian enterprises?
Rehosting (lift-and-shift) moves workloads to cloud VMs with no changes. Replatforming makes targeted modifications — migrating to managed databases, containerising applications, or upgrading middleware — to unlock cloud benefits like auto-scaling, managed patching, and reduced operational overhead. Opsio recommends replatforming when Indian enterprises want cloud value without full refactoring risk and timeline.
Which Indian workloads benefit most from replatforming?
Database-heavy applications (moving from self-managed to RDS, Azure SQL MI, or Cloud SQL), middleware-dependent workloads (WebLogic to containers), and .NET Framework applications (upgrading to .NET 8 on App Service) see the greatest benefit. Opsio assesses each workload in your Indian portfolio for replatforming suitability, considering complexity, risk, cost, and expected cloud benefits.
How does replatforming reduce costs for Indian enterprises?
Replatforming to managed services eliminates DBA, middleware, and OS administration overhead — typically reducing operational costs 30-50% compared to self-managed cloud VMs. Indian enterprises also benefit from auto-scaling that matches Indian business traffic patterns, reserved instance pricing for predictable workloads, and elimination of middleware licensing costs like WebLogic or WebSphere.
Can Opsio replatform legacy Java applications for Indian enterprises?
Yes, Opsio replatforms Java applications from legacy app servers (WebLogic, WebSphere, JBoss) to modern runtimes — Spring Boot on containers, AWS Elastic Beanstalk, Azure App Service, or Google Cloud Run. We handle dependency analysis, build system modernisation, and configuration externalisation while preserving business logic and ensuring DPDPA-compliant deployment in Indian regions.
What is the typical timeline for replatforming Indian enterprise workloads?
Individual workload replatforming takes 4-8 weeks depending on complexity. A portfolio of 10-20 applications typically completes in 3-6 months using Opsio’s factory approach with parallel workstreams. We design replatforming waves around Indian business calendars, regulatory freeze periods, and stakeholder availability — with rollback procedures at every stage to protect production operations.
