Not sure if this is the right spot,
But Im tasked with upgrading my new employers Mail system from Ubu8.04LTE (zimbra 5) to UBU12LTE and the latest version of Zimbra. All Open Source Editions.
I will also be moving to new hardware...
Im pretty new to Linux, and have zero Zimbra knowledge.
can anyone suggest the most practical way to complete this.. (there is no money for external contractors)
I What I think I need to do
1. upgrade to V7 x32 (on UBU 8 still)
2. migrate to the x64 version on UBU8.0.4 LTE
3. upgrade UBU to the latest Version
4 Upgrade Zimbra to the latest version.
does this sound like the most practical option??
