We have recently upgraded our Windows servers from 2012r2 to 2019 and would like to raise the AD from 2012 to 2019 but I would like to know if that will cause any effect on our cifs shares that NetApp is hosting.
SMB2 is on. I did check, and the only smb1 connections are coming from my Unitrends backup appliance. It has SMB2 enabled so I am not sure why it is connecting via smb1. I assume if I don't disable smb1 on the NetApp that will continue to work.
