I have an Ubuntu server that I had a friend running a JIRA installation on. We want to back up his JIRA installation such that he can migrate it to his own server now that he has one, leaving me room to install my own copy of JIRA for my own use. Problem is, I can't get ahold of the guy right now, and I'd really like to get my own JIRA going ASAP.
Given that I have root access to my server, is there any way I can back up everything from my friend's JIRA installation such that he can easily migrate it in, when I can't log into thie JIRA installation to do an XML export? Can I just do an SQL dump and make a copy of the application-data directory, will that work?
