We have a setup on CIFS connected to an existing Windows 2008 domain. The customer has merged with another company and will eventually need to migrate his domain to the new Windows 2008 domain of the other company. Re-joining the NetApp to the new domain isn't an issue. However, they have existing File and Folders on Windows 2008 permissions, which need to be migrated to the new domain. For their existing Windows server, they are migrating using ADMP - this will migrate their computer accounts, users, groups, etc. It doesn't work on the filer though.
