Hello everyone,

I am supporting a client whom is upgrading their existing email server with more than 300 mailboxes using Exim + Horde + Apache + MySQL + Kerberos to Zimbra Network Edition.

Questions:
1) Are there any Zimbra or external tools, utilities or scripts to automate the migration of user accounts and mailboxes to Zimbra NE?

2) Does anyone have any pre-deployment checklist so that I can do a trial migration to ensure success of the migration?

Thank you for your replies. I promise to write a HOWTO Guide and share it with everyone if I can get support on the above-mentioned questions.

Regards,
Moonshi
