Cloud migration can help businesses modernize applications, improve resilience and scale IT resources. But moving workloads without a clear plan can introduce downtime, unexpected costs and security gaps. This cloud migration checklist for Indian businesses helps teams plan each stage before moving production systems.

1. Define business goals and migration scope

Start by documenting why you are moving to the cloud. Common goals include improving availability, enabling remote access, modernizing legacy applications or reducing infrastructure maintenance. List the applications, databases, file shares, dependencies and business owners in scope.

2. Assess workloads and dependencies

Classify workloads by business criticality, data sensitivity, performance needs and compatibility. Map application-to-database connections, identity systems, integrations, backup processes and network dependencies. Identify systems that need refactoring rather than a simple lift-and-shift.

3. Choose the right cloud approach

Compare public cloud, private cloud and hybrid models against compliance, latency, skills, resilience and cost requirements. Evaluate AWS and Microsoft Azure using the same workload assumptions instead of comparing headline prices alone.

4. Build a realistic cost estimate

Include compute, storage, network egress, backup, security tools, monitoring, support, licensing and migration effort. Define budgets and alerts, right-size resources, and review usage after workloads stabilize. Cloud spend should be measured against business outcomes, not just the old data-centre bill.

5. Design security before migration

Use least-privilege access, multifactor authentication, encryption, secure key management, network segmentation and centralized logging. Review data residency and contractual obligations where relevant. Test backup restoration and document incident-response responsibilities before cutover.

6. Plan connectivity, backup and disaster recovery

Estimate bandwidth and latency requirements for users, branches and applications. Define recovery time objectives (RTO) and recovery point objectives (RPO), then test whether backup and disaster-recovery designs meet them. Keep a rollback plan for critical cutovers.

7. Pilot, migrate and validate

Move a low-risk workload first. Test functionality, integrations, access permissions, response times, monitoring and data integrity. For production migration, agree on a maintenance window, stakeholder communications, go/no-go criteria and rollback triggers.

8. Optimize after go-live

Monitor availability, performance, security findings and spend. Remove unused resources, schedule non-production workloads where appropriate, review access regularly and assign service owners. Migration is complete only when operations are stable and measurable.
