I make a backup of my /opt/zimbra folder every night.
Tomorrow night I will attempt to upgrade form 5.0.16 OSE to 5.0.20 OSE. If something doesn't go right. Will I be able to just rm -rf /opt/zimbra then extract my backup in its place, then startup zimbra? In theory?
Also, I have a backup server already in place. However it is on 5.0.20. If for some reason I needed to use that, would my backups of 5.0.16 work? I don't imagine they would, but I figure it doesnt hurt to ask.
Thank you in advance.
