This is a interesting question:
We have JIRA v7.4 running and when I look in the jira folder it shows jira atlassian-jira-4.4.4-standalone ONLY in the folder. When I look in the /usr/home/ it shows the other developer(who is no longer here) downloaded v7.4. I tried to see if they were linked together with a ls -lrt but only the list showed up. Some how they are synchronized together. Any helpful ideas to see where they are sync together? As I have to do a upgrade to 7.7. Thanks in advance!
