RSAT Is Being Retired: What Should D365 F&SCM Teams Switch To?
Microsoft has confirmed the retirement date for the Regression Suite Automation Tool (RSAT): May 15, 2027. For teams responsible for regression testing in Dynamics 365 Finance & Operations, that's a clear signal to start planning a migration now, before the tool stops receiving updates and, potentially, stops working properly inside D365 environments.
A year and a half is enough time to approach this calmly, but not enough to ignore it. The regression-testing workload itself isn't going anywhere – every Dynamics 365 One Version update still needs to be tested, and the larger an existing test suite is, the longer it takes to move it to a new tool.
A free RSAT alternative: Testing Freemium by XPLUS
One option worth knowing about is Testing Freemium by XPLUS, a free entry tier of the Testing by XPLUS platform built specifically for teams migrating off RSAT. The key difference from rebuilding a suite manually is that it imports existing RSAT and Microsoft Task Recorder recordings (.axtr and .xml files) directly, so nothing has to be re-recorded from scratch.
The product includes an AI Optimizer that helps stabilize imported scripts when the D365 interface changes, while a human reviewer stays in control of every suggested change. It covers Dynamics 365 Finance & Operations, Business Central, and the wider Microsoft BizApps suite, and getting started requires no credit card and no time limit. XPLUS is a Microsoft Solutions Partner and an AppSource-certified ISV, and the tool itself can be found and activated straight from the Microsoft Marketplace listing.
RSAT vs. Testing Freemium: the main differences
Both tools are free to start, so the real difference is runway rather than price. RSAT has a fixed end date; Testing Freemium is an actively maintained commercial product with no such deadline.
- Future support - RSAT stops receiving updates on May 15, 2027; Testing Freemium continues to be developed with no end date.
- Setup - RSAT requires Azure DevOps familiarity and technical configuration; Testing Freemium is ready to use immediately, with existing recordings imported directly.
- Migrating existing tests - not needed for RSAT, since it's the native format; Testing Freemium imports RSAT and Task Recorder files without any rebuild.
- Maintaining scripts after D365 UI changes - RSAT needs manual re-recording; Testing Freemium's AI Optimizer assists with stabilizing scripts instead.
- Platform coverage - RSAT only supports D365 F&O; Testing Freemium also covers Business Central and BizApps.
- Path beyond the free tier - RSAT has none; Testing Freemium offers an upgrade path to the full Testing by XPLUS platform for larger volumes and dedicated support.
How the migration actually works
Moving off RSAT takes four steps and doesn't involve manually rebuilding test cases: exporting existing recordings as XML files from RSAT or Task Recorder, importing them into Testing Freemium (where they're automatically converted into ready-to-run test cases), running and editing the imported scenarios, and scaling up once the approach has been validated.
What's actually included in the free tier
The free tier includes 150 test cases per instance and 1,200 test runs per year - a hard annual cap. Once an account hits that limit, testing pauses until the next year begins or until the account is upgraded. The free tier also includes one user running test playback at a time, background test execution, and multi-tenant server hosting. Dedicated support isn't part of the free plan; paid L1/L2/L3 support packages are available separately for teams that need them.
Who is this a good fit for?
Testing Freemium fits teams currently on RSAT that need a replacement before the May 2027 deadline, already have an RSAT or Task Recorder library they don't want to rebuild, and run a suite that fits comfortably within the free-tier limits. It's also a reasonable way to pilot automated testing for the first time, or to cover both D365 F&O and Business Central at once.
Larger organizations - running hundreds of test cases across frequent release cycles, needing multiple concurrent test sessions, or requiring dedicated support – are better served by the full, paid Testing by XPLUS platform.
