Hi,  Please, take a look at manual "Configuring and Managing CIFS on Celerra" on powerlink.   Updates all SIDs from a source domain to the SIDs of a target domain by matching the user and group account names in the source domain to the user and group account names in the target domain. The interface specified in this option queries the local server and then its corresponding source and target domain controllers to search each object’s SID. Review the following before using server_cifs -Migrate command option: > The migrate option does not require running any type of domain migration tool beforehand. > For the migrate option: • The source and target domain controllers must exist. • As long as a trusted relationship is established between the source and target domains, you can specify the same interface or NetBIOS name in the server_cifs command. • To use different interfaces or NetBIOS names, you must configure two separate CIFS servers on the Data Mover for the source and target domains.    Replaces the history SIDs from the old domain with the new SIDS in the new domain. The interface that you specify in this option queries the local server and then its corresponding target domain controller to search each object’s SID and history SID.  Review the following before using server_cifs -Replace command option:  > The replace option requires that you first perform account migration by using a domain migration tool.> The replace option provides one quota per user or group.

We are planning to migrate from one Active Directory Forest to new one. Most of the job is done by using ADMTv3, Exchange cross-forest migration etc. We have bunch of file systems on Celerra with various NTFS permissions. We need to migrate permissions for DOMAIN1\User1 to DOMAIN2\User1. For Windows servers we would just use ADMT. Obviously it cannot be used for Celerra as it installs ADMT Agent on Windows. Is there nice EMC Celerra way/tool to do this or we will have to just access it by \\CIFSServer\share and use some custom script?
