i have a server with CentOS 5.7 64-bits + Zimbra NE 7.13
But i need migrate to new server with CentOS 6.2 64-bits + Zimbra NE 7.13.
I do a single test following this Moving ZCS to New Server - Zimbra :: Wiki
without success. This wiki say that only work with 6.x and 5.x Zimbra versions.
Any ideas to do it safe and no losing data?
