We are currently in the process of rebuilding our infrastructure from 2003 SBS to Server 2012 R2. One of the tasks I am faced with is the migration of the file server. I am currently testing this out before we go live. I was able to recreate all users and groups in the on the test environment running 2012. I am looking for a way to copy the NTFS permissions or set the permissions as they were in the previous environment. I am building the new domain with the same namespace as the existing domain and using the same server names. I use acronis for backup and with the option to restore NTFS permissions, I get the correct rights set, however, the entries are for SIDs of the users in the old domain. I am able to restore the data successfully, however, I need the ability to back up and restore the NTFS permissions to the new domain. Any utility which will allow me to set the permissions via username instead of SID?
Any assistance with this would be very much appreciated.
