Then I think you will also have to write a reverse migration script to convert all the
data back into the old format. I suggest you do this to a different server than the
original server. Then use mysql-table-checksum to verify you got exactly the same data
I think this is your only option because you must compare the data to the authoritative
copy of it, in the original format, if you want to make sure it is all correct in the
If you can convert both directions without loss, I think that is as strong a guarantee
as you can get.
