How to do it...
To manually upgrade your Jira instance, perform the following steps:
- Take your current Jira offline.
- Install the new version of Jira in a different directory.
- Edit the jira-application.properties file in the JIRA_INSTALL/atlassian-jira/WEB-INF/classes directory to point to the existing JIRA_HOME directory.
- Copy any modified files from the old Jira instance to the new one.
- Start up the new Jira instance.
- Update the add-ons once Jira starts successfully.
- Remove the previous installation directory to avoid confusion.
