Currently I have Zimbra installed on multiple servers as follows:

Server for Zimbra LDAP on 1 box.
Server for Zimbra Mailbox on another server.
Server for Zimbra MTA on another server.

I would like to consolidate all these services back onto 1 Server, is it as simple as just installing zimbra with all the services on 1 box and then doing a restore onto his new server? Or what is all necessary to make it so I can move it back onto 1 server versus 3 servers?

Please Advise would be greatly appreciated.
