A Microsoft tool designed to automate database migration to SQL Server from Access, DB2, MySQL, Oracle, and SAP ASE.
In the SQL Server migration component in SSMS, the Feature Parity assessment type is only available for specific target scenarios.
According to the migration component behavior:
- Compatibility Type is used to identify breaking changes, behavior changes, and deprecated features for upgrades between SQL Server versions.
- Feature Parity is specifically for discovering partially supported features when migrating cross‑platform, and the note states this option is enabled when the target is SQL Server on Linux.
Because of this, when a different target platform (such as SQL Server 2025 on Windows or other non–Linux targets) is selected, the SQL Server feature parity option is expected to be disabled (greyed out). It becomes active only when the target platform matches the supported cross‑platform scenario (for example, SQL Server on Linux).
