Hi
I have a test server Jira software with a trial license key.
I have a complete SQL backup of our Jira software production to test restoring on this trial server. And after restoring I have :
"
License Too Old For Build: We found a problem with your JIRA license
Your current Jira Software license doesn't allow you to upgrade to this version of JIRA (8.1.0). Jira Software expired on 02/Apr/19 3:00 PM, and you can currently only upgrade to versions released prior to this date. Alternatively you can renew your license at my.atlassian.com which will allow you to upgrade to this version of JIRA (8.1.0). You can enter your new license here.
See our documentation for more information on licensing errors."
Then I suppose that server ID and/or license is not equal between bdd and something else!
