Hey Rafael,  Please use the tools EMCOPY or ROBOCOPY for data migration on VNXe.
We are planning to migrate from one Active Directory Forest(2000) to new one(2008 in 2003 Forest Functional Level). Most of the job is done by using ADMT. We have bunch of file systems on VNXe 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 VNXe 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?
