I inherited a Zimbra server version 4.0.1_GA_324 32 bit on Centos 4. I need to migrate it to a new machine and upgrade to a current version.
As it stands it looks as though I need to migrate first to Centos 5.5 machine, then upgrade the version of Zimbra as far as I can, then install another Centos 6.x and migrate a second time then run the additional upgrades.
Is this correct? is there a more direct way to get to the current version from that far back? Am I doomed to a lost weekend of mail server migration?
Thanks for any help!!!
