Migration in flight — sound familiar?
- ▸ CLR assemblies + SSIS with no equivalent — Aurora PG via SCT converts T-SQL but stops at CLR; SSIS packages need a full Glue or AWS DMS rewrite. The migration plan didn't budget for this.
- ▸ Always-On AG split-brain at cutover — The secondary that should have promoted didn't — both sides accepted writes for 4 minutes during the failover window, and you have inconsistent state.
- ▸ License audit mid-cutover — You switched Edition during the migration (Enterprise → Standard, or Web → Standard) and the auditor now wants per-core licensing back-dated to the cutover.

SQL Server Migration Services
In short: A SQL Server migration covers version upgrades to 2022, on-prem to Azure SQL, and Oracle/MySQL/PostgreSQL cross-platform moves, run through a six-step process — assessment, planning, schema and object migration, data migration with CDC, testing, and cutover. Always On AG rolling upgrades deliver sub-30-second cutover windows with full data-integrity validation.
