We intend to migrate all the accounts under a domain hosted on Zimbra 6.0.6 Opensource to Zimbra 6.0.6 Network Edition hosted at another data center. Is there any tutorial or best practice for doing this? Is zmztozmig the right tool to use?
Our initially plan is quite time consuming:
1. Recreate all domain accounts one by one at Zimbra Network Edition and update MX record to have new mails to get to the Zimbra Network Edition server
2. Export all domain accounts one by one at Zimbra Opensource to portable harddisk
3. Bring the harddisk to the data center and import all domain accounts one by one into Zimbra Network Edition
