AWS Cloud Migration Consulting — Plan & Execute
Cloud migration without a strategy is just expensive chaos. 65% of enterprises exceed their migration budget because they skip the assessment phase and discover dependencies, compliance gaps, and architecture mismatches mid-flight. Opsio's AWS migration consulting provides the planning, architecture design, and hands-on execution that ensures your workloads land on AWS optimised, secure, and within budget.

What is AWS Cloud Migration Consulting?
AWS cloud migration consulting provides expert assessment, strategy development, architecture design, and execution support for moving on-premises or co-located workloads to Amazon Web Services — covering compute, storage, databases, networking, security, and compliance.
Migrate to AWS With Confidence, Not Chaos
Moving to AWS promises agility, scalability, and cost savings — but the migration itself is where most organisations stumble. Without proper assessment, workloads are lifted-and-shifted onto oversized EC2 instances that cost more than the on-premises servers they replaced. Database migrations stall because application dependencies were not mapped. Security configurations are left permissive because the team planned to tighten them later. The average enterprise migration takes 2-3x longer than planned because of these preventable surprises. Opsio's AWS cloud migration consulting starts where it matters most: a thorough assessment of your current environment. We use AWS Migration Hub and custom discovery tools to map every server, database, dependency, and data flow. From that foundation we build a migration strategy aligned to the AWS 7Rs framework — Relocate, Rehost, Re-platform, Refactor, Repurchase, Retire, or Retain — choosing the optimal approach for each workload based on business criticality, complexity, and cost-benefit analysis.
Our certified AWS architects then design the landing zone: VPC architecture, IAM policies, security groups, encryption, logging, and compliance guardrails using AWS Control Tower and Organizations. We execute migrations using AWS Database Migration Service, CloudEndure, and custom tooling with zero-downtime cutover strategies including DNS failover, database replication, and blue-green deployments. Post-migration, we right-size instances, implement Reserved Instances and Savings Plans, and configure monitoring with CloudWatch and CloudTrail.
What We Deliver
Migration Assessment & Discovery
Automated discovery of servers, databases, applications, and dependencies using AWS Migration Hub, Application Discovery Service, and custom tooling. Dependency mapping, TCO analysis, and migration complexity scoring for every workload.
Landing Zone Architecture
Multi-account AWS architecture using Control Tower, Organizations, and Service Control Policies. VPC design with transit gateway, security groups, NACLs, and private link. IAM policies, encryption standards, and logging with CloudTrail and Config.
Database Migration
Schema conversion and continuous replication using AWS DMS for Oracle-to-Aurora, SQL Server-to-RDS, MongoDB-to-DocumentDB, and other migration paths. Zero-downtime cutover with change data capture and validation testing.
Server & Application Migration
Automated server replication with AWS MGN (CloudEndure) for lift-and-shift, re-platforming to containers on ECS/EKS, and refactoring to serverless with Lambda and Step Functions. Each approach matched to workload requirements.
Cost Optimisation
Right-sizing analysis using AWS Compute Optimizer, Reserved Instance and Savings Plan recommendations, spot instance strategies for non-critical workloads, and ongoing cost monitoring with AWS Cost Explorer and Budgets.

AWS Cloud Migration Consulting — Plan & Execute FAQ
How long does an AWS cloud migration take?
Timeline depends on the number of workloads, complexity, and migration strategy. A focused migration of 10-20 servers with straightforward re-hosting takes 6-10 weeks including assessment. Enterprise migrations involving 100+ servers, multiple databases, and application refactoring typically run 4-9 months in phased waves. Opsio accelerates timelines by running assessment and landing zone preparation in parallel and migrating workloads in overlapping waves.
What does AWS migration consulting cost?
Assessment and strategy engagements run $15,000-$40,000 depending on environment size. End-to-end migration execution ranges from $50,000-$300,000+ based on workload count, complexity, and required refactoring. Most clients see 25-40% reduction in infrastructure costs post-migration, delivering ROI within 12-18 months. We provide detailed cost estimates during the assessment phase with transparent pricing and no hidden fees.
Can we migrate databases without downtime?
Yes. AWS Database Migration Service (DMS) supports continuous replication with change data capture for Oracle, SQL Server, MySQL, PostgreSQL, and MongoDB. We set up ongoing replication from source to target, validate data consistency, then perform a brief cutover (typically minutes) during a maintenance window. For zero-downtime requirements, we implement application-level dual-write strategies with automated failback capability.
What is the AWS 7Rs migration framework?
The 7Rs classify migration strategies by effort and transformation level: Relocate (VMware to VMware Cloud on AWS), Rehost (lift-and-shift to EC2), Re-platform (minor optimisations like moving to managed databases), Refactor (re-architect for cloud-native), Repurchase (replace with SaaS), Retire (decommission), and Retain (keep on-premises). Opsio assesses each workload against all seven strategies and recommends the approach that delivers the best cost-benefit ratio.
How do you ensure security during migration?
Security is designed into the landing zone before any workload migrates: encrypted data transfer using AWS PrivateLink and VPN, IAM least-privilege policies, security group rules, encryption at rest with KMS, and logging via CloudTrail and Config. We perform security validation at every migration wave and conduct a post-migration security review to verify that all controls are correctly applied in the new environment.
