Team, I currently have Zimbra 4.5.6 Running BEAUTIFULLY on my Ubuntu 6.06 server. I want to go to the latest 5.x train on Zimbra for some of its features so I figure now is the time to bite the bullet and upgrade the O.S. as well. My question is the order in which to do this. Ubuntu 6.x to 7.10 first or Zimbra 4.5.6 to 5.x first?? Any experience or caveats are appreciated.
Any thoughts or suggestions are also welcome.
