کاروبار داؤ پر لگائے بغیر پرانے پلیٹ فارم سے نکلیں

Legacy system modernization updates or replaces software running on outdated technology while preserving the business logic and data it holds. Approaches range from wrapping the system in APIs, to migrating its interface to a modern platform, to replacing it module by module. Full rewrites are the highest-risk option and are usually a last resort.

Rewrites are attractive and frequently disastrous, because the old system encodes years of edge cases nobody has documented. Incremental modernization - replacing modules behind a stable interface - is slower but keeps the business running. We recommend a full rewrite only when the existing system is genuinely beyond extraction.

We extract it from the code and the data, and we validate it against real users and real historical transactions. Parallel running is the safety net: the old and new systems process the same inputs until outputs reconcile, which surfaces the rules nobody remembered.
