Keeping a Dynamics NAV system stable after the partner walked away

When its previous partner stopped supporting Dynamics NAV, a UK manufacturer turned to FITS to keep the business running – and to plan the future.

The challenge

The company relied on a heavily customised Dynamics NAV system for production, stock and finance. Its partner decided to leave the NAV market, which left the business without anyone who understood the custom code, the server environment or the year-end routines.

With mainstream support for older NAV versions long over, the board also needed a realistic answer to a bigger question: how and when to move to Business Central without putting operations at risk.

Our approach

Knowledge captureOur NAV developers reviewed the custom objects, documented what each modification does and which processes depend on it.
StabilisationWe reviewed the SQL Server and service tier setup, backups, job scheduling and performance, and fixed the most disruptive faults first.
Reliable supportThe client received a named team with long-standing NAV experience, a ticket portal and agreed response times.
Business Central roadmapWe mapped each customisation to standard Business Central features, AppSource apps or extensions, and prepared a phased migration plan.

The results

Business continuityProduction, stock and finance kept running without interruption during the handover.
Custom code under controlThe modifications are documented and understood – no more black box.
Fewer surprisesPerformance and job queue problems were addressed proactively.
A clear path to the cloudThe board has a costed, phased plan for moving to Business Central.

What made the difference

Our team has long-standing Dynamics NAV experience. That meant we could read and maintain legacy code confidently, while also knowing exactly which customisations Business Central now makes unnecessary.
