Can't able to start JIRA after upgrading it from 7.6.X to 8.4.X

[rashmi.bisoi]

While upgrading Jira 7.6 to 8.4 we could not able to start upgraded Jira instance.

After checking the atlassian-jira.log file we got the following issue.

I'd suggest you to kill all JIRA processes - do a fresh restart , ensure that your id has all permissions under JIRA filesystem and check the logs again as it restarts.

Also check catalina.out log.

Also, the user id that you used to upgrade - is it the same as the one that was used to initially install jira or if it is different - does it have all the required permissions under JIRA filesystem - application and home directory.

When you did the upgrade - did you specify everything correctly ?

Looks like post upgrade the properties files dont point to the right home directory of JIRA.

[rashmi.bisoi]

We have cross checked the home directory path.

jira.home = D:\\Atlassian\\Application Data\\JIRA

It's the exact path of Jira home directory.
