I am trying to determine the most painless way to perform the following:
We are upgrading to a new Mail Server, Lates version of Zimbra(NE) and also with the recent discussion regarding CentOS support, we will be moving to Ubuntu.
1. Ubuntu Site lists LTS 6.06.2 dl instead of 6.06.1 (listed in the support doc). Does this matter?
2. Our new machine is 64 bit capable, are their any caveats to using the 64 bit OS with 5.0.2 NE?
3. What I would like to do is install Ubuntu, then ZCS, on the new machine, then restore from a backup from the old machine. Something tells me this won't work. (our current Version is 4.5.6)
About 75% of our users are using POP, the others using Outlook Connecter & Mobile.
I'd appreciate any advice or input from others who have done similar. Zimbra version upgrades have been a breeze in the past, but switching to a new box and OS is making this one a little more challenging.
