I'm looking to upgrade our existing production server to 8.0.7. What are the necessary steps I should take to upgrade with minimal downtime and no data loss?
Release 8.0.6.GA.5922.UBUNTU12.64 UBUNTU12_64 FOSS edition.
I was looking into ZeXtras as a backup solution but don't have the funds to purchase it right now. Used it for a previous migration and it worked great. I figured I could backup the /opt/zimbra directory to another folder since I have tons of space on the server, then proceed with the upgrade.
We have about 110 user accounts, several distribution lists and aliases, and probably about 10GB of mail in total.
What would be the best path to take to upgrade while minimizing downtime and avoiding data loss?
My last upgrade was a migration using ZeXtras to a brand new VM so I didn't have to worry about an inline upgrade.
I'd like to do this soon, so any help or advice you can provide would be great.
