Our approach & solution
enreap executed a phased migration strategy using AWS Application Migration Service (MGN), covering discovery, AWS environment setup, continuous replication, test migration, and controlled cutover. The approach ensured minimal risk, zero critical data loss, and seamless transition, while maintaining clear alignment with customer-managed application and database responsibilities.
AWS Foundation Setup
Established a secure AWS foundation with VPC, subnets, gateways, IAM roles, and MGN staging environment aligned with best practices.
Migration Execution & Validation
Enabled continuous replication, performed test migrations, validated OS and application readiness, and resolved issues prior to production cutover.
Controlled Production Cutover
Executed the migration within the planned maintenance window using the latest replicated data, ensuring minimal disruption.
Auto Scaling & Operational Readiness
Configured and validated Auto Scaling for eligible workloads, delivering a secure, scalable, and production-ready AWS environment.
Continuous Server Replication
Migrated 14 Ubuntu and 1 Windows server using AWS Application Migration Service (MGN) with continuous data replication.
