Migrating Zimbra from Release 5.0.8 CentOS5 FOSS to Release 7.0.0 CentOS5_64 FOSS
I recently was asked to migrate our Zimbra mail server because there is concern that the server hardware is going to fail. I believe I will be migrating it with the same domain name. Anyways, I've been a Zimbra user where I work, but I haven't done anything like this before. I've seen threads for moving from release 5 -> 6 and 6 -> 7, but where I work they've already installed 7 on a virtual machine and the current mail server is running version 5. I signed up on these forums hoping somebody could help me out a bit.
Does it make a difference migrating from a 32 bit version to a 64 bit version?
What do I need to do?
I figure if they just had the same release version I would just be able to shut down the mail server and mysql, back up the files and move them over (maybe edit some permissions). But I'd think moving up 2 releases would nix that idea. Any help would be GREATLY appreciated. :o
