All right so here's the scenario.
An external forest level trust is setup between two forests A & B as recently as we acquired the company B.
Users from forest B were already migrated to domain A.
Now I need to migrate file server from domain B to my domain A but the target where we need to move file shares is a NAS device, so basically we cannot do a simple server migration from domain B to domain A.
We need to copy over the data+ACL+Share permissions from fileserver in domain B to a NAS device in domain A whereas of course ACL permissions on file server present in domain B will obviously be as per source domain user accounts, example ACL permissions currently will show as "B\user1".
So whats the best way to perform this in order to maintain the permissions & data.
Another question how do we copy share permissions from file server to NAS as I can robocopy the data with security permissions but how to copy over all the share permissions to destination NAS?
