When I say "Add in interoperability of hashing functions", that is pretty much exactly what I mean. I realize I left out the specific method for converting the hashes over. And your separate column for when the hash has been converted is the equivalent of my suggesting for a HashVersion column. Also, you will likely never be able to "quietly remove the old way" because not all of your users are guaranteed to log in again. But yes, the idea would be to verify against the old hash, save the new hash when the user logs in.
