Microsoft MDS is reaching end of life
MDS was removed from SQL Server 2025. SQL Server 2022 — the last version that includes it — loses mainstream support on July 9, 2028. That is the real deadline to move your master data off MDS.

MDS was removed from SQL Server 2025. It remains available in SQL Server 2022, whose mainstream support ends July 9, 2028. After that, MDS only exists on software outside mainstream support, with extended (security-only) support ending in July 2033.
No — if you are on SQL Server 2022 you have until July 9, 2028. But you should not wait for a forced SQL Server upgrade to discover MDS is gone. Evaluate alternatives and run a proof-of-concept migration now, while you can run both systems in parallel.
Primentra is a self-hosted, like-for-like MDS replacement on the same SQL Server foundation. Its built-in migration wizard exports your MDS models with one SQL query and imports them — entities, attributes, hierarchies, and domain values — in minutes.
Don't wait for the upgrade that breaks MDS
