You upgraded to SQL Server 2025 — or you're planning to. And then you see it: Master Data Services is not available. Not deprecated, not reduced in scope. Gone. The MDS installer doesn't exist in SQL Server 2025 (17.x). If your organization has built data governance, reference data workflows, or MDM processes on MDS, you have a real problem to solve — and a narrowing window to solve it.
This article covers exactly what happened, what your replacement options actually are (beyond the vendor sales pitches), and why SQL Server teams are increasingly landing on Primentra as the practical middle ground. For the full alternatives breakdown, the 2026 MDS alternatives comparison covers every major option with pricing.
What Happened to Master Data Services
Master Data Services has been part of the SQL Server stack since SQL Server 2008 R2. For fifteen years it was Microsoft's native MDM answer — a web-based application for defining data models, enforcing business rules, managing hierarchies, and controlling edit permissions. It had its quirks (anyone who wrestled with the Excel Add-in knows), but it did the job. It was free, on-premises, and spoke SQL Server natively.
Microsoft's official documentation now lists MDS and Data Quality Services (DQS) as removed from SQL Server 2025 (17.x). Both features remain supported only through SQL Server 2022 (16.x). The message is clear: if you're running MDS today, you have a migration deadline whether you've acknowledged it or not.
What MDS Actually Did — And Why It's Hard to Replace
MDS wasn't flashy, but it covered a real set of problems. You defined models, entities, and attributes through the web UI. Business users edited data via the Excel Add-in or the browser interface. Hierarchies let you structure product categories or org charts. Role-based security controlled who could view, edit, or approve. A subscription system staged changes before they were committed — a primitive but functional approval workflow.
For SQL Server teams, the killer feature was that everything lived in a proper SQL Server database. You could write T-SQL against it, query it from ETL pipelines, back it up like any other database. The tool had real limitations, but it lived in your environment, spoke your language, and didn't require a cloud subscription or a six-figure contract.
Finding a replacement that checks those same boxes — on-premises, SQL Server native, no per-record pricing, with real workflow and permission controls — is genuinely harder than the MDM vendor landscape makes it look.
Microsoft MDS Alternative: How the Options Actually Stack Up
The options fall into three buckets — and two of them probably won't fit your situation.
Enterprise MDM platforms — Profisee, Informatica, Stibo, Semarchy, Reltio — are all real products, and all serious. They also come with a procurement process, a vendor kickoff meeting, and a bill that lands somewhere between $50k and "we'll need to talk to your CFO." If you have a dedicated data governance team and a multi-year MDM roadmap, they make sense. Most SQL Server shops replacing MDS don't have either.
Cloud-native governance tools — Microsoft Purview and Azure Data Catalog — are Microsoft's official post-MDS direction. But they're cloud-mandatory and solve a different problem. If your organization runs on-premises SQL Server and needs data authoring, workflow, and permissions on reference data, these aren't a drop-in replacement.
Build your own — some teams try to replicate MDS in a custom app. It usually works fine until the person who built it leaves. Then you have a custom MDM application that nobody fully understands, that doesn't get upgraded, and that breaks whenever someone touches the schema.
The middle ground — purpose-built MDM tools designed for exactly this scenario. Affordable, opinionated enough to get you running in days, flexible enough for real data models. That's where Primentra sits.
Why Primentra Is Built for MDS Teams
Primentra was built for SQL Server teams that need MDS functionality without the enterprise price tag or the implementation timeline. If you've used MDS, the concepts map directly: models, entities, attributes, role-based permissions, approval workflows. The main difference is that it installs in an afternoon.
Rebuild Your MDS Model in Hours, Not a Sprint
Define models, entities, and attributes through the UI — no code, no web service restarts. The structure is the same as MDS; the setup is faster.
The Same Security Model Your Team Already Knows
Permissions work at the entity level: read, edit, approve, admin. Group-based, role-based, exactly what MDS users expect — without the XML configuration.
Nothing Goes to Production Without the Right Sign-Off
Changes are proposed and routed for approval before they're committed. You get a real audit trail — not just who changed what, but who approved it and when.
Your DBA Can Maintain It. No New Stack to Learn.
Every entity maps to tables and stored procedures in your own SQL Server database. T-SQL works. ETL pipelines work. Backups work exactly the same as before.
The Migration Path Is Shorter Than You Think
You don't have to cut over all at once. Stand up Primentra alongside your MDS installation on SQL Server 2022, replicate your models, import your data, and train your users — all without touching production until you're confident.
Primentra's built-in migration wizard handles exactly this scenario. Export your MDS entities and master data, import them with a few clicks, and your data model is running in the new environment. Both systems run on SQL Server, so your ETL pipelines and stored procedures point at a new database name — that's usually the extent of the rework.
The goal isn't to migrate perfectly on day one — it's to have a working, tested replacement ready before SQL Server 2025 forces your hand. See all Primentra features →
How it works — start to finish
Don't Wait Until the Upgrade Forces Your Hand
Start the evaluation now and you have time to test, train, and migrate properly. Wait until SQL Server 2025 is on your upgrade list and you're picking a Microsoft MDS alternative under deadline — which is not when you want to be negotiating a six-figure MDM contract.
Primentra's 60-day free trial is designed for this evaluation window. Install it on your own SQL Server instance, import a few of your MDS entities, and see how it maps to your workflows. No cloud migration. No professional services. No credit card. Start your 60-day free trial →
MDS did the job for fifteen years. Its removal is annoying, not catastrophic — the functionality it provided still exists, just not in SQL Server anymore. If you're on SQL Server and need a tool that speaks T-SQL, stays on-prem, and doesn't come with a six-month onboarding process, that's exactly what Primentra is for. The MDS migration guide walks through exactly how to move your models and data across. See pricing →
