I'm migrating and upgrading JIRA (3.11 to 4.3.4) and the original installation has all the indexes, attachments, backups etc. in the install directory!!
When installing the new version, I've set JIRA Home as a seperate folder from the install dir.
So, the question is, what's in the Home directory (what do I need to copy out of the old install directory into the new home directory before I import my XML data into the new version)?
