Excellent guide: Moving ZCS to Another Server » Zimbra :: Blog
I've followed this guide to reinstall my server from scratch and move it to a new system.
I just need to figure out one thing. I'm going to be switching to a 64bit OS. Is it going to be ok to do this exact same procedure and just replace Step 2 of Part 3 and Step 5 of Part 4 with the 64bit version of Zimbra?
Or will I be better off using the 32bit version of Zimbra and do an upgrade to 64bit after everything has been switched over?
