Probably the wrong place to ask this question, but need to know! A client wants to migrate from Zimbra 7.2.1_GA_2790.RHEL5_64_20120815212042 CentOS5_64 FOSS edition to Exchange 2010. Can the Zimbra Migration Wizard for Exchange be run in reverse to move the mail from Zimbra to Exchange? Or does it only work from Exchange to Zimbra? It would make sense that it goes in both directions (in the case of a migration) in case you need to roll back a mailbox for whatever reason.
