there should be a db upgrade script that automatically detects current schema version and does do migration to latest
So if we have 7.0 current schema and the latest is 8.1 this new script should discover that and then run in a row:
- ./upgrade_7.0_to_8.0.sh
- ./upgrade_8.0_to_8.1.sh
It will make user life easier and doest not force user to figure out current schema version.
