best path from Zimbra 6.08 FOSS debian5 32 to zimbra 8.02 NE ubuntu12.04 64 bit ?
Having put off upgrades for a long time, I think it's time to bite the bullet and upgrade my zimbra install to the latest version.
At the same moment, I'd like to go from the FOSS to the NE Starter Edition.
My config now: Debian 5.09 - 32 bits - Zimbra 6.0.8 FOSS
My goal: Ubuntu 12.04 LTS - 64 bits - Zimbra 8.0.2 NE Starter Edition
I've settled on Ubuntu because it is similar to Debian ( which I know & prefer).
Is this a recommendable path? the hope is that each step induces the least amount of 'pain'
1) debian 32 > debian 64 bits - Zimbra 6.08 FOSS
2) debian 64 > ubuntu 10.04 LTS - Zimbra 6.08 FOSS
3) Zimbra 6.08 FOSS > zimbra 8.02 FOSS - Ubuntu 10
4) Ubuntu 10 > 12.04 - Zimbra 8.02 FOSS
5) Zimbra FOSS > NE
