Why the retirement of RSAT should prompt organizations using Dynamics to rethink their validation capability, not just their choice of tool.
The retirement of RSAT creates a visible sense of urgency: Microsoft has confirmed that the Regression Suite Automation Tool will no longer be supported after May 15, 2027. For organizations using Dynamics 365 Finance and Operations, the natural response will be to quickly look for a replacement tool. But this transition raises a more important question: how can they maintain long-term confidence in the updates that affect critical business processes?
That reaction is understandable. RSAT has helped many teams structure an initial approach to regression test automation and make validation less dependent on scattered manual efforts.
But limiting the discussion to a tool replacement would be a missed opportunity.
The question is not only: “Which tool will replace RSAT?”
The real question is: “How will we sustainably validate our Dynamics updates?”
Because updates will not disappear with RSAT. Critical processes, integrations and business operations will still need to be validated with rigor.
RSAT’s retirement is therefore more than a date on a calendar. It is a turning point for reassessing how an organization ensures the quality of its updates over time.
Why tool replacement alone is not enough
When a tool nears the end of support, the market’s reflex is quick: propose an alternative. Some solutions emphasize artificial intelligence, others script migration or ease of execution.
But in the reality experienced by many Dynamics organizations, the obstacles to successful automation are not always purely technical.
Many teams already have automation tools, yet the expected return is not always there. The barriers lie less in the tool itself than in operational reality: maintaining scenarios, mobilizing the right experts at the right time, absorbing the pace of updates, and keeping test coverage aligned with the real evolution of processes.
This reality has guided the evolution of Alithya Rapid QA: helping organizations move from tool-centered automation to a validation capability that can keep pace with change, frequent updates and operational pressure.
Testing Dynamics is not the same as testing the business process
Another element deserves attention in the post-RSAT transition: the real scope of validation.
Historically, initiatives around RSAT focused mainly on Dynamics 365 Finance and Operations. That approach made sense when the goal was to validate processes executed primarily within the ERP.
But today’s environments are often more interconnected.
A critical business process may now span Dynamics 365 Finance and Operations, Power Platform, customer or supplier portals, web applications, document management solutions, APIs or custom-built applications.
In this context, an organization can replace RSAT with another tool and still retain a significant risk area if its validation strategy remains limited to a single application.
The question then becomes: are we validating only Dynamics, or are we validating the complete business process?
This nuance is essential. A Dynamics update can affect process chains that extend beyond the boundaries of the ERP. For some organizations, Dynamics-centered coverage will be sufficient. For others, integrations, peripheral applications and cross-functional processes will represent a significant portion of the risk to control.
For example, an update that subtly changes a behavior in Dynamics may appear under control if the main transactions pass testing. But if that transaction then triggers an exchange with a supplier portal, a billing API or a document management system, the real risk may be elsewhere in the chain. This is often where validation limited to a single application reaches its limits.
This is where an approach leveraging Alithya Rapid QA can play a broader role than simply replacing RSAT: supporting the validation of transactions in Dynamics, but also the sequences that span integrations, portals, APIs and the systems that make the process truly operational.
Across projects, one observation comes up often: the organizations that achieve the best results are not necessarily those with the most sophisticated tool. They are the ones that have clarified their critical processes, understand which validations truly create confidence, maintain their test coverage at the pace of change, and have a realistic model to sustain the effort over time.
From tool transition to sustainable validation capability
Choosing a new tool remains important. But it should be guided by a more structuring conversation: what will need to continue being validated, by whom, how often and with what level of support?
This reflection helps avoid a superficial migration. It is not only about transferring scenarios from one tool to another, but about defining how validation will be maintained, governed, and adapted to the real evolution of processes.
This is where Alithya Rapid QA can support the transition in a concrete way. Its RSAT converter helps preserve part of the work already completed, while transforming existing scenarios into a starting point for a more complete, more maintainable approach that is better aligned with today’s business processes.
From that foundation, Alithya Rapid QA can then support different needs: reuse and evolution of test assets, automation of Dynamics scenarios, validation of broader processes, integration with delivery practices and support based on the organization’s maturity level.
The value then depends on how this capability is maintained over time.
Depending on the client’s reality, support can take different forms: full autonomy, progressive enablement, or targeted support during updates or managed services. The right model depends on the team’s maturity, the criticality of the processes, and the capacity available to maintain scenarios over time. The goal is not to impose a single approach, but to maintain confidence in Dynamics updates year after year.
Maintaining confidence beyond replacement
RSAT’s retirement is an important event, but the main risk would be to treat this transition as a simple tool replacement.
The organizations that will get the most value from this transition are those that use it to clarify their validation capability, their test coverage, and the model that will allow them to maintain this discipline over time.
Replacing RSAT is relatively simple. Maintaining confidence in Dynamics updates year after year is a much more strategic challenge.
This is where Alithya Rapid QA and our expertise can contribute: by helping organizations build a useful, maintainable validation capability aligned with the reality of their operations. The objective is not only to migrate scripts, but to preserve confidence in the processes that keep the organization running.
