Legacy Modernisation with Dynamics 365, Azure & Power Apps
Seers modernised legacy business applications for a federal financial services regulator by replacing unsupported Lotus Notes solutions with a cloud-first Microsoft stack, improving usability for internal teams and external users and establishing reusable architecture patterns.
What they were up against
The regulator needed to modernise a set of legacy Lotus Notes applications that were no longer vendor-supported and were increasingly limiting both staff and external user experiences. The legacy environment also relied on manual, paper-based processes, driving delays, rework, and inconsistent outcomes.
What we did
- Discovery and design to capture requirements, define technical solution architecture, and produce UX prototypes for stakeholder sign-off
- Implementation using a pragmatic hybrid delivery model combining upfront alignment with agile build and iterative release
- Modern Microsoft delivery using Azure, Dynamics 365, and Power Apps and Power Forms
What changed
The result was a replacement solution with an improved look and feel, strong adoption across internal teams and external users, and architecture patterns that could be referenced for broader reuse.
