Hi Websense,
Some feedback for the upgrade process from 7.8.4 to 8.1. On the whole it has been a great experience. The documentation is excellent and almost everything went as planned, but!
When I upgraded my Linux WCG I couldn't get the management UI to open. After several re-installations (thank goodness for VM snapshots) I worked out that the custom SSL cert I had configured for the Web UI was not preserved during the upgrade. I had copied in a new cert named differently than "server.pem". The config to use this cert was copied across, but the certificate itself was lost.
If I backed up the certificate from /opt/WCG/config and restored it after the install and restarted WCG everything else worked.
Perhaps you could update the documentation to reflect this.
Regards,
Jeremy Hagan
