Pre-Upgrade Steps
Before upgrading your Zimbra platform, we would strongly recommend the following pre-upgrade steps:
0. Always read (in full) the Release Notes for the version to which you are upgrading. The Release Notes are available for every release:

1. Backup your system:
There are multiple ways to perform backups. Since upgrading permanently alters your system, it is mandatory to backup your system before you upgrade. The only recovery from a failed upgrade may be to restore from backups:
a. zmbackup your entire system:
