500 error page after JIRA upgrade

After upgrading error, JIRA shows the 500 error page with the following log message:

java.lang.IllegalStateException: User 'admin' has no unique key mapping.

The name of the user will be usually the administrator user and might differ based on your user configuration.


The following appears in the atlassian-jira.log:

The current license is too old to install this version of JIRA (6.x.x).


For all upgrade methods, one of the pre-steps is to check that the current JIRA license is valid. If the license had expired before the upgrade, then it will lead to this error message. This is tracked as a known bug  JRA-37644 - Getting issue details... STATUS .


Please follow the workaround section from  JRA-37644 - Getting issue details... STATUS .
