Migration & Transformation
What is Data Migration?
Extracting, transforming, cleansing, loading, and validating data from legacy systems into a new ERP.
It covers master data, open items, balances, and selected history. Multiple mock loads refine mapping and quality. Data migration defects are among the most common go-live blockers.
