Risk of Disabling SNMP

[TMADOCTHOMAS]

We have enabled SNMP on all of our NetApp clusters over the years. Now I would like to disable it as I'm aware it is considered insecure. Is there any loss of functionality in the following NetApp tools / features if I disable it? Is there any way to easily determine if it's being used in some way?

• Active IQ
• Active IQ Unified Manager (in particular the EMS Events functionality)
• OnTAP Tools
• SnapCenter
• SnapCenter Plug-In for VMware
• PowerShell Toolkit

Alternatively, we could switch to SNMPv3 which of course is more secure, but I'm not sure what effect that transition would have. Any ideas out there?
