Express Install (use default settings) [1], Custom Install (recommended for advanced users)                                                                                                           [2], Upgrade an existing JIRA installation [3, Enter]

Existing installation directory:
[/opt/atlassian/jira]

Back up JIRA home directory
The upgrade process will automatically back up your JIRA installation
directory. You can also choose to back up your existing JIRA home directory.
Both directories are backed up as zip archive files in their respective
parent directory locations.

We strongly recommend choosing this option in the unlikely event that you
experience problems with the upgrade and may require these backups to
restore your existing JIRA installation.

If you have many attachments in your JIRA home directory, the zip archive of
this directory may consume a significant amount of disk space.
