I have a server instance and have just tried to upgrade exactly as per the recommendations, only to be told that my (and I assume every other server users) expired license does not  allow the upgrade. If it is not possible for Server Users to upgrade at all would you please remove that section entirely and replace it with some useful recommendations.

Updated the ticket with Mitigation options

1. This fix was included in the Confluence Cloud Migration Assistant plugin (which we sometimes refer to as CCMA), and version 3.9.5 (or later) contains the fix. So for a mitigation step, all you need to do is login to Confluence as an admin, select General Configuration >> Manage Apps and then locate and upgrade the CCMA plugin to 3.9.5 or later. Confluence upgrade is not required in this case.
2. The other option is you can deactivate the CCMA plugin altogether if don't plan for the upgrade.
