error when trying to update the system from 6.2.7 to 7.1.9
first, I updated to version 6.4
then to version 7.1.9
and then appeared an error "Unexpected exception during JIRA startup. This JIRA instance will not be able to recover. Please check the logs for details"
I checked database for Null. And nothing found
then, I found the inactive users and replaced them
error is not missing
I then removed the home/jira/cashes/indexes home/jira/plugins/.bundled-plugins and .osgi-plugins
and renamed installed-plugins
but all this did not help, I still see the error at startup jira. in the logs also do not see anything that could help me
