AD functionality level with CIFS

[JA_THOMAS01]

We currently have a project underway to upgrade our domain functionality level from Server 2008R2 to Server 2016. Trying to find a reference as to what versions of ONTAP are supported or any thing I need to be aware of when this upgrade occurs. Does anyone have any experience doing this, or point me in the direction of any resources?

Running a combination of ONTAP 9.0 - 9.3 across multiple sites. All clusters serve CIFS file shares, joined to the domain in question. 

Thanks,

James

Hi JA_THOMAS01,

Have no fear updating your domain functional level. Just make sure every CIFS client in your AD is using the correct SMB version.

You can find supported versions in ONTAP here.
