Inventory dependencies, define recovery and approach migration in verifiable stages. The sections below outline a useful way to evaluate the work, choose sensible next steps and avoid expensive assumptions.
Inventory before migration
Document applications, database engines, integration endpoints, authentication flows, certificates and scheduled tasks. List who depends on each service and which systems are business-critical. This creates a scope for the migration rather than a broad infrastructure guess.
Define availability and recovery
Agree how much downtime the business can tolerate and how much data loss would be acceptable in a disruption. These recovery objectives shape backup frequency, deployment patterns and rollback plans. Test restoration rather than assuming backups will work.
Make security part of architecture
Apply least-privilege access, secret management, network segmentation and logging from the beginning. Moving to managed cloud services does not automatically remove the organization's responsibility for access controls and sensitive data handling.
Migrate in measurable stages
Separate lower-risk components and validate connectivity, performance and data consistency. Use a cutover plan with owners, checkpoints and a clear rollback trigger. For database migrations, coordinate writes carefully to avoid split-brain or lost transactions.
Optimize after stability
Once the application is reliable, measure real utilization and cost. Review observability, storage policies, autoscaling behavior and resilience. Successful migration is not only the day an application starts in the cloud; it is the operation that remains maintainable afterward.
