First port of call:

And on that page there is a link:

Check out the button:

Scroll down to the switch type of interest, and determine if your Cisco Cluster Switch needs an upgrade.

For example (data correct as of 25.04.2021):
Nexus 3232C:
Reference Configuration Files
ONTAP 9.3 – 9.8 : Cluster RCF_v1.0
Recommended Cluster NX-OS Versions
ONTAP 9.8, 9.7, 9.6, 9.5 : 9.3(4), 7.0(3)I7(9)
