Would a backup of the cPanel partition be enough if mysql upgrade goes wrong?
The recent cpanel update notes I should update my mysql 5.5. I noticed the thread at: notes that it's impossible to revert back from MariaDB back to mysql 5.5.
Would a backup of the drive that contains cpanel, whm, apache, etc. allow me to revert back, if "things don't work right" on the database driven sites?
An upgrade to MariaDB doesn't change data in the /home directories or the actual mysql database files, is that correct?
So I could simply restore the backup, and be back on mysql 5.5 if things didn't go right with the "recommended" MariaDB 10.3?
I'm very concerned as some sites are 5-10 years old, and I have no one that can rewrite our code to get it working on a newer mysql/MarioDB version. It has to continue to work, otherwise I can't use a new version.
