I cant find the kb you mentioned but I believe in Unity you can just change the name in the GUI

should be possible in Unity by just changing it in the GUI

I would suggest to create a test NAS server and just try it

This is basically what the SR i mentioned said, for the VNX.

1. Unjoin the original compname from the domain:
   
   # server_cifs  server_2 -Unjoin compname=W2k3,domain=abc.com,admin=Administrator
   
   
2. Delete the compname from the Data Moverâ„¢s CIFS configuration:
   
   # server_cifs server_2 delete compname=W2k3
   
   
3. Add the name back to the Data Moverâ„¢s CIFS configuration as a Netbios name:
   
   # server_cifs server_2 add netbios=W2k3,domain=abc,interface=fsn01
   
   
4. Rename the Netbios server to the new name:
   
   # server_cifs server_2 rename -netbios W2k3 W2k3prod
   
   
5. Delete the newly renamed NetBIOS name from the Data Moverâ„¢s CIFS configuration:
   
   # server_cifs server_2 delete netbios=W2k3prod
   
   
6. Add and join the new Compname to the CIFS configuration and AD domain:
   
   # server_cifs server_2 add compname=W2k3prod,domain=abc.com,interface=fsn01
   # server_cifs server_2 Join compname=W2k3prod,domain=abc.com,admin=Administrator

We also migrated data from the VNX to Unity with this procedure and it worked just fine. We did the new share's on unity with correct names and only SMB computer name was named as a "sharename-new". After file migration we just unjoined share from the domain in the VNX and renamed the SMB computer name in the Unity to remove the -new from computer name. Just remember not to be too fast in share renaming in unity after unjoining the VNX share from the domain. AD replication takes time to delete old VNX share's computer objects from all the AD servers. (with multi site AD design it takes even longer).

It is possible. But don't just rename the NAS Server itself in Unisphere. You need to go to the properties of the NAS Server, select the Sharing Protocols Tab and change the SMB Computer Name. As soon as you tab out of the name field, the domain user and password fields are activated and you need to re-enter the Domain User credentials.

I have done this in a test and a production environment. I migrated a NAS server from Celerra to Unity, where the CIFS Server name had to carry over to the Unity. During the cutover phase, I renamed the old CIFS Server using the VNX procedure you mentioned above, and then renamed the Unity NAS Server using the method I just described.

KB emc156835 is now "353215" - https://support.emc.com/kb/353215

Also, I see that in the "Unity Family Unisphere CLI User Guide" and the "Unity Family Service Commands" documents there are commands for CIFS - you might want to see if those have the tools that you could use.

SteveK's message with Unity screenshot is spot on and also validated through EMC case I filed.
