I have migrated JIRA (v6.3.15) and Confluence (5.7) to a new debian server. I downloaded the respective .tar.gz files (not EAR/WAR) from the download archive page and extracted these into their respective newly created install directories (/opt/atlassian/JIRA and /opt/atlassian/confluence). Both systems are small and are currently configured to use the embedded database.
Following the instructions at https://confluence.atlassian.com/doc/migrating-confluence-between-servers-184150.html I have successfully started JIRA on the new server, added my current starter license, and performed a restore of the xml backup from the old server.
On the old server, Confluence was configured to share JIRA users. But now, when I start Confluence on the new server, the login fails - "Sorry, an error occurred trying to log you in. Please try again." Of course, trying again also fails.
I have re-created the Application Link to Confluence, but when being redirected to Confluence to apply the reverse link, the call fails.
Is there a way to create an administrator user in Confluence, or force a login somehow, so that I can recreate the Confluence Application Link manually?
Or is there another way out of what appears to be a Catch-22 situation?
