Step 7: Upgrade additional Filtering Service, Network Agent, and User Service machines

If you have additional Filtering Service, Network Agent, or User Service instances, upgrade them next, regardless of what other services reside on the machines. Filtering Service, Network Agent, and User Service may reside on:

• A Windows Server machine.
• A RHEL machine.

See the Certified Product Matrix for a list of supported operating systems.

Filtering Service and Network Agent may also reside on filtering only appliances.

When Filtering Service or the management server is upgraded from v8.1, v8.2, or v8.3, the Cloud App Agent component is added to the machine.
