Legacy System Modernisation for Nonprofit and Public Sector

We map your current data structure, validate integrity at each stage, and run parallel systems during the cutover to catch discrepancies. Audit trails, historical records, and compliance metadata move intact. We test recovery procedures and keep rollback paths open until you're confident the new system is stable. This is especially important for charities holding donor or beneficiary data and public bodies managing citizen records.

Refactoring improves the code and architecture of your existing system incrementally, often moving it to the cloud while keeping the same core logic. Full migration replaces the system entirely with modern software. Refactoring is lower-risk and faster to value. Full migration gives you a cleaner slate but takes longer and requires more change management. We assess your system's technical health and your team's capacity before recommending which path fits your nonprofit or public body best.

Yes. We've worked with UK public bodies through formal procurement frameworks, tendering, and governance boards. We provide detailed timelines, fixed-scope phases, and transparent costing. Our UK leadership and nearshore delivery team means you have a clear point of contact who understands how public sector projects work and can attend board meetings, procurement reviews, and stakeholder sessions if needed.

We audit your current system early to find custom code, undocumented logic, and third-party integrations. We often extract this logic into services or rebuild it in modern languages. If integrations are tied to vendors no longer in business, we replace them with modern alternatives. Knowing what you have is the first step. We document all findings so your team understands the new system as well as we do.

Simple migrations with clean data can take 3-6 months. Complex monoliths with years of technical debt, multiple integrations, and strict compliance rules take 6-18 months. We break work into phases so you see value quickly and can adjust as you learn. For nonprofits and public sector organisations, phased delivery also spreads costs and reduces the operational risk of moving everything at once.

Yes, new systems require training and a period of adjustment. We provide documentation, video walkthroughs, and on-site or remote training sessions during and after the transition. We also maintain the system during the ramp-up period so your team can focus on learning while we handle technical support. Many nonprofits and public bodies pair this with a post-launch support retainer so there's continuity once we hand over.
