If you have any specialized needs, or would like to learn more about the migration options and how they can be used to make sure your migration is performed in an appropriate way for your organisation, please refer to the advanced options.

Zimbra Proxy Servers

When migrating from Zimbra, CloudM Migrate opens direct connections to the servers hosting the mail, and ignores the Zimbra proxy server (if one exists). This is done to workaround a bug in the Zimbra APIs. If CloudM Migrate cannot connect to the mailbox servers, the migration will fail. To ensure CloudM Migrate can connect, you should ensure the servers are available via DNS, or edit the hosts file on the migration servers to allow resolution.
