Hi All

 
         Currently I have a domain server (physical one) also this is a file server as well, and the file storage is in a SAN Storage, and we will plan to install a new domain server with different domain name, and we will also plan to move the LUN from the SAN storage to map to the new domain server (in vm), just wonder will the NTFS Permission remain in the new domain server ? before the LUN move from the current domain server to a new one, we will build a trust between the 2 domain server and use a Quest Dell migration tool to migrate domain user, computer & SID to a new domain server, any help would be appreciated, Thanks !

The LUN will continue to hold the NTFS permissions itself but it will be for the original domain. Even with a forest trust you will still need to apply the permissions accordingly to the users in your new domain.

Once you have done this you can use the ADMT to migrate the server/shares to the new domain.

So that I will need to move the Lun and map to the new domain vm server before using the migration tool to migrate user accounts ? i will be using dell migration tool and I will rename the current domain user to different name such as from "andychan" to "achan" (since the dell migration tool have a feature to rename account) , after I migrated for Andy, the NTFS permission for Andy will remain in the Lun ? But I still need to manually add "achan" in the NTFS Permission ?

That is correct, when you attach your LUN to another domain all of the SID will not match up. If you have a trust with or migrate the users and keep SID history intact then it should work when you present the LUN to your new server in the other domain.

Note: if you have any Shares on this LUN you will need to re-create all of them as the Share Names are stored in the Registry of the server where it is being shared from.

As I only has shared the root parent folder with everyone full access, all the subfolders has NTFS permission, so that after the Lun move and mapped to new domain I only need to shared the parent folder out, and I wish that I do not need to modify any NTFS Permission after the Lun move and user migrated, will the NTFS permission automatically changed from "andychan" to "achan" in the NTFS permission ?

You will have to add the users from the new domain to this share unless you have a 2 way forest trust enabled.

my plan now is to move the LUN from the current domain controller to one of the member server in the current domain, and then trust the new domain, I think the ntfs permission will still remain in the member server

That is correct. However, if you have any shares on this LUN you will need to re-create them. Shares are tied to the machine itself and this info is stored in the registry.

before using the migration tool, do I need to do anything on the client computer ? such as below ?

1.      add target domain administrator account in local admin group
2.      add new server’s dns ip address on client computer
3.      check window firewall, make sure Upnp and enable
