Although Build a multi-year TCO comparing infrastructure, licensing, operations, transfer and exit costs can be valid when A migration business case considers EC2 price but excludes existing colocation termination penalties, it targets a different technical condition. A valid business case accounts for one-time and recurring source and target costs.

Include temporary dual-run periods and postcutover decommissioning milestones in cost models would address a different requirement: A proposed migration claims savings despite permanent double-running of source and target databases. Overlap and delayed shutdown can reverse expected cost benefits.

This alternative, Include patching effort, availability operations and resilience benefits alongside cost in the assessment, is appropriate when A database workload is moved to a managed service and business owners ask about qualitative benefits. Managed service value includes reduced operational toil beyond instance-hour charges.

This alternative, Include application-level smoke tests, authentication validation and rollback acceptance gates, is appropriate when A migration wave reports server replication success but transactions fail after cutover. Replicated infrastructure is not equivalent to an operationally accepted application.

For the separate situation A migration sponsor needs measurable success criteria for each wave instead of a list of completed VM copies, Define business transaction, error-rate, latency, data integrity and recovery acceptance thresholds could be useful. Objective service-level gates distinguish successful migration from resource movement.

Require controlled decommissioning and cost/ownership confirmation after successful cutover solves the related scenario An organization moves one application but leaves its original servers running indefinitely; completing a wave includes retiring unneeded source infrastructure.

Although Select low-risk representative applications for the first pilot wave can be valid when A migration program wants to validate tools without risking its most critical revenue platform, it targets a different technical condition. Pilot waves expose process gaps without putting the highest-impact service at risk.

Schedule coupled services with coordinated compatibility and data cutover plans would address a different requirement: Ten services share a database and cannot tolerate mixed client versions during a staged move. Shared state dependencies make arbitrary wave separation unsafe.

For the separate situation A workload must preserve unsupported local hardware dongles and cannot run in EC2, Retain or redesign the hardware-dependent component rather than forcing an MGN rehost could be useful. Replicating server disks does not make unsupported physical dependencies cloud-compatible.

Test the licensing behavior in a launched migration test and preserve the source rollback path solves the related scenario A legacy Linux application needs a rollback window because licensing behavior on EC2 is uncertain; validation before production cutover reduces irreversible migration failures.

Although Perform MGN test launches and validate application dependencies before cutover can be valid when A source server is replicating but the target EC2 test instance has never executed the real workload, it targets a different technical condition. Server replication health alone does not prove target runtime and connectivity work.

For the separate situation A legacy Linux application needs a rollback window because licensing behavior on EC2 is uncertain, Test the licensing behavior in a launched migration test and preserve the source rollback path could be useful. Validation before production cutover reduces irreversible migration failures.

Although Keep continuous MGN replication and coordinate the cutover window and final launch can be valid when A server migration requires short downtime and ongoing source-write replication until the final launch, it targets a different technical condition. Incremental block replication minimizes changes left to transfer at cutover.

Retain or redesign the hardware-dependent component rather than forcing an MGN rehost would address a different requirement: A workload must preserve unsupported local hardware dongles and cannot run in EC2. Replicating server disks does not make unsupported physical dependencies cloud-compatible.

Use AWS Application Migration Service for continuous block-level replication and planned cutover solves the related scenario A Windows and Linux fleet must move from VMware to EC2 with minimal application rewrites; mGN supports lift-and-shift server migration with replication and test launches.
