Migrate From Microsoft MDS

From Microsoft SQL Server Master Data Services to Lima master data

Master Data Services is removed in SQL Server 2025 and supported on SQL Server 2022 and earlier, so the database platform's next upgrade ends the free hub.

An illustrative move

Anonymised pattern

A mid-size distributor with six MDS models (customers, products, sales territories, chart of accounts, cost centres, units) moved them in three weeks. Subscription views were replaced by SQL views with the same names, so the BI reports kept working; the Excel add-in users moved to the grid's spreadsheet-style editing.

Questions

What happens to the consumers of the old hub?

They move behind a router one at a time: SOAP consumers get a generated WSDL, SQL readers get views with the same names, API consumers get REST with the same shapes.

Can we keep the old hub for reference?

Yes, read-only, for as long as your retention policy needs; its history is already searchable in Lima.

What is the fixed price based on?

The inventory: the count of domains, sources, rules, hierarchies and consumers, written before the work starts.

Bring two systems that hold the same customers, suppliers or materials. In one working day we connect them, run the match on live rows, review the queue with your steward and publish the first golden view with its API.
