System Upgradation & Migration at GPRN Software
Overview

How we help

Legacy applications become slow, insecure and hard to support. We modernise them: upgrading frameworks, moving to new databases or the cloud, and rebuilding old screens on modern technology, while keeping the business logic your team relies on.

Data is migrated in rehearsed steps with reconciliation checks, and we run old and new systems side by side until you're confident to switch over.

Where it fits

FAQ

Common questions

Can't find your answer? Write to info@gprnsoftware.com.

Will there be downtime?

We plan the final switch for a quiet window; in most projects downtime is a few hours or less.

Can you keep our existing reports and logic?

Yes. Business rules and stored procedures are carried over or rewritten to behave the same way.

What if something goes wrong at cut-over?

Every migration has a tested rollback plan, so you can return to the old system if needed.
