We have a JIra server license expired on 12/04/2021 04:00 and we are trying to upgrade from 8.14.0 to 8.16.0 released on 23/03/2021 according to
https://confluence.atlassian.com/jirasoftware/jira-software-8-16-x-release-notes-1044110509.html
So the version is covered by our license but we can not update anyway?
"Your current Jira Software license doesn't allow you to upgrade to this version of JIRA (8.16.0). Jira Software expired on 12/04/2021 04:00, and you can currently only upgrade to versions released prior to this date."
Downgrade to 8.15.0 fails with the same message.
Downgrade to 8.14.0 fails entirely with failed plugin report.
