Hello everyone!
I am trying to upgrade our JIRA instance from version 7.4 to 8.1. When I try to run the installation wizard and choose Upgrade an existing JIRA installation it shows that i have an existing JIRA installation directory, but it points to a wrong directory(in fact to a directory that doesn't even exist). Funny thing is that when i choose Custom or Express install, it points to a correct installation directory and when i select it, it says JIRA is already installed there.
I can't change the installation directory either.
What might be the issue and how can i resolve this? This situation is critical and fast feedback is greatly appreciated.
Thank you in advance.
