Thanks a lot for the work on this- may I suggest a step before the next step (after rebuilding) of "checking all data, old and new, is consistent". This is a lot of data, and even on well thought processes missing rows were discovered after I requested a comparison on other well-though migration, which happened due to mistakes/existing inconsistencies/aborts. May I request such a step, which could be as fast as a simple join query (<5m to run) between old an new to check no rows are missing or extra, and have equivalent data?
