Hi, in my enterprise we have a Fedora Core 3 server running with the following services:
-Postfix (with clamav and spamassassin through amavis)

I want to install zimbra in this server, my question is if this is possible and some tips with migrating the existing configuration to Zimbra. Some important points are egroupware contacts, mailboxes (unix account's mailboxes) and egroupware calendar.

Thx and my apologies for my english.
