Idea Kunena 1.6 known issues

Kunena 1.6 migrates ALL data to the new kunena tables structure. The old fb tables are kept as a backup copy.

Yes, I was thinking that way. So.. if i uninstall K 1.6 and install 1.5.x it will be still working with fb_ tables like before?

Yes it does, but be careful:

Any data entered while on 1.6 will not make it back to the old fb tables and will appear to be missing. Also when you reinstall 1.6 it will see the existing 1.6 tables and will not perform another data migration. Otherwise ever future 1.6 upgrade would migrate old data over and over, potentially overriding new changes.

So if you need to go back you have to make a conscious decision to do so and when back on 1.5 you really should drop all 1.6 tables before you want to upgrade again. This will require access to the underlying database, good backups and technical skills that many normal site admins might not posses. This definitely falls into the category of advanced...
