Hi @RogerLevy -- the import process should be fine, there aren't any major breaking changes.
In fact, if you really want, our upgrade scripts are supposed to be idempotent, so you can run them again (by deleting the schemaLog value from the database) so that ./nodebb upgrade runs them all again.
Alternatively, delete individual items from that sorted set.
Alternatively, run individual upgrades by executing ./nodebb upgrade upgrade_script_name 😄
Lots of options!
