It says to do the following to upgrade your vShield Edge devices
Upgrade vShield Edge on each port group in your datacenter.
1 Log in to the vSphere Client.
2 Select Views > Inventory > Networking.
3 Click the vShield Edge tab.
4 Click Upgrade. .
Since we have many vShield Edge appliances in our configuration I wanted to know if there was a way to upgrade them in bulk rather than clicking on each port-group, then vShield Edge, and upgrade? Could I via the vCloud Director Administrative Portal reset all the NAT networks causing the VSE to be re-deployed bringing it to a newer version? We have at least 100 port groups in our configuration, so going through each port-group using the recommendation in the documentation will be very time consuming. My thoughts are if I can 'Reset Network' on each NAT network with a VSE then I can go about completing the VSE more quickly.
