A 2-4 week assessment package for understanding legacy data structures, exports, reporting dependencies, and migration constraints in licensing and certification systems.

Legacy migration work here is centered on safe sequencing, data understanding, validation, and practical modernization rather than risky big-bang replacement language.

A workable legacy data migration plan defines exports, wrangling, transformation, imports, exchange controls, cutover sequencing, and rollback. Planning quality determines whether modernization reduces risk or introduces new fragility.
