After upgrading to the latest Bamboo (6.10.4) I have some issues(*), I wonder if I could downgrade to 6.9.2. I don't see any official guide to downgrade. I easily could swap the binaries (as I do in an upgrade), but I guess on the startup the database is upgraded too, so I don't know if the old binary would work with the upgraded database structure... (The release notes doesn't mention if any of DB upgrade happened).
I could revert my changes from the backup, but then I would loose weeks of build history, what I really don't want, the downgrade would really help.
(*): I have issues with the agents connection, that's another topic, I going to open a ticket for the support, but the quick solution still would be the downgrade.
