Answer

Hyper-V over SMB support nondisruptive operations (NDOs).
If you configured a Hyper-V over SMB solution, the application servers and the contained virtual machines or databases remain online and provide continuous availability during the ONTAP upgrade.
 
Continuously available CIFS shares, which are accessed by Hyper-V Server clients using the SMB 3.0 protocol, no need to be terminated before upgrading or downgrading.
