Upgrade the Portal Servers

Perform server upgrades in the following order:

1. Upgrade the CTERA Portal main database server.
2. Upgrade the CTERA Portal catalog node server(s) (if applicable)
3. Upgrade the CTERA Portal application server(s).

Do not proceed with upgrading the next CTERA Portal server before ensuring the CTERA Portal services in the previous server are up and running.

For each server, upgrade the CTERA Portal OS image and then upgrade the CTERA Portal software.
