I use zimbra network edition version 6.0.6
I want to upgrade next week to version 7.1.1, do i have to upgrade to other version prior to this or i can upgrade directly to version 7.
Also the backup is made in /opt/zimbra/backup, i will copy this for safety in another place , is there anything else i need to backup except this ? All the settings will remain the same , users/password etc... ?
Thank you for your help
