Migrating a VNX with CIFS form one domain to adifferent domain

Hi guys I want to migrate a VNX with CFS form one domain to another. I was thinking to do the below steps. Let me know if they are right.Let’s say my old domain is old_domain and new domain is new_domain and my CIFS server is server1

1) Migrate the sid’s in the acl database for all file systems. Server1 is the cifs server, old_domain is old domain and new_domain is new domain, cge1 is the name of the interface on the VNX. FS1 is one of the file systems on the VNX

Server_cifs server_2 –Migrate FS1 –acl old_domain.com:nb=server1:if=cge1 new_domain.com:nb=server1:if=cge1

2) perform the AD count migration using quest tools

3) Run the replace ommand

Server_cifs server_2 –Replace FS1 –acl:nb=server1:if=cge1

4) Unjoin the existing CIFS server1 from the old domain

Server_cifs server_2 compname=server1,domain=old_domain.com,admin=****

5) Remove the cifs server configuration from the Celerra Data mover

Server_cifs server_2 –delete compname=server1

6) Recreate the CIFS server on the data mover specifying the new domain name and interface

Server_cifs server_2 –J compname=server1,domain=new-domain.com,interface=10.x.x.x,admin=*****

Thanks a lot
