My server is running Ubuntu 6.10 and my version of Zimbra is currently 5.0.19. I want to install new/bigger drives and install Ubuntu 8.04. I've since found a Power Tip on Moving ZCS to Another Server.
Has any one has done this and are there any hidden gotchas?
I'm making room on my NAS for the backup. How can I determine the correct size of backup space required?
