I have been tasked with upgrade a pre-production server and have no experience with JIRA before now.
In following the directions provided in https://confluence.atlassian.com/adminjiraserver/upgrading-jira-applications-using-the-installer-938846937.html
I selected the option to upgrade as directed in 6.2.a
In section 6.2.b of this document it alludes to the system reporting existing Jira installation dirctory(ies). While I see the default directory /opt/atlassian/jira comes up for the prompt "where should JIRA Software be installed?" The issue becomes by selecting this directory I am greeted with
"It appears that JIRA is already installed in the directory you selected. Please choose a different directory."
So please help me understand. The "Upgrade" documentation says nothing about how to handle this nor to move existing installations to other directories or ... et al. What am I do here? Create a new installation?
