I plan to downgrade my ROCK NUC from 2.0 to 1.8 Legacy this weekend.
Are the database from 1.8 and 2.0 the same type? Do I need to restore database from my 1.8 database backup?
I am asking because whenever we upgrade, the initial screen usually shows that the database is being optimized due to the upgrade/update or something similar to that meaning.
But if we downgrade, would that database optimisation for the newer version be compatible with the older version?
Currently the databases are 100% compatible between 2.0 and 1.8 Legacy and this was by design. There is no need to restore from backup, just install 1.8 Legacy and go.
