Migration that creates the greatest amount of cleanup is often the one with the fastest transit time.

There’s always pressure to move quickly; tight deadlines, stakeholders monitoring progress, and an expected go-live date which was set before any work had even begun.

Speed has become the ultimate measure of success.

But speed without validation does not save time – it borrows it back later with interest. Bypassing or rushing validation and you risk data issues going undetected for years after cutover; users dealing with disruption from cutover when it should have been addressed prior to it taking place instead.

I prefer delivering a migration that takes slightly longer and is fully validated than one that meets its date but results in two weeks’ worth of cleanup tickets.

Speed does matter; however, it should not be seen as the deciding factor of whether a migration has taken place successfully or not.
