Zimbra Admin Level on Exchange Migration

[wfweaver]

We have a new client who is migrating from their Exchange server to our hosted Zimbra service. We have some confusion regarding the admin level necessary on the Zimbra side to run the Exchange Migration Wizard. If we set up the domain in Zimbra and provide a user with Domain Admin permissions to it, is that sufficient or does the Wizard need full Admin rights on Zimbra in order to migrate? Obviously as a hosting company we are certainly hoping that domain admin is sufficient for this process!
