The challenge in any complex data migration is not just to move data from an old system into a new system. 


The real challenge is to do it a way that ensures the business logic is moved or transformed in a way, consistent with the new system.

We make the case for using a solution already specifically developed for complex data migrations to save time, money and ensure quality of outcome.
