Last year, I upgraded from Jira 6.4 to 7.3, and probably missing something, it displays the following at the top of each page:
***********************************
JIRA Software is currently unavailable. This might be because an upgrade task has failed to run or has not yet completed.

I'm with MySQL 5.7.x on Windows platform, would like to upgrade to the latest version Jira 7.11.
Should I upgrade by using the procedure of 7.3 to 7.11, or should I fix this problem first?
