Moving from Open source 4 to 5

[davidgeller]

I'm setting up a new server to run the open source edition of Zimbra and would like to migrate all the messages in our version 4.5.11_GA_1751 open source version, running on a different server.

Is there a migration assistant when working with two different servers so I can move all the mailboxes and their contents to the new system? Thanks in advance.

no automated migration asstant, but otherwise its fairly simple.
you can follow the link word by word and that is all you need

* you should update your profile with zimbra version and OS platform..some steps for 64 bit are different.
