Update nodes from SNMPv2 to SNMPv3

Why not use web node management, you can update multiple nodes at once there.

Excellent! This works well as long as the SNMP versions are the same. I tried to select all of them but then the SNMP option dissapeared. Digging further I found some had SNMPv1 and others SNMPv2. If I select all SNMPv1 or SNMPv2 then it allows me to select SNMPv3 and do a bulk update.

Good call.
