I am migrating our Jira Db from OnDemand to our own server ... and I must restore a particular project b/c Jira was already implemented on our server before the new team decided to use OnDemand, then changed their minds. 
I'm using the instructions at https://confluence.atlassian.com/display/JIRA/Restoring+a+Project+from+Backup
But I'm getting validation error I can't figure out how to solve:
Issue Link Type
The Issue Link Type 'Epic-Story Link' has style 'jira_gh_epic_story' in the backup, but has no style in the current system.
I added the JIRA Agile add-on to get the Epic and Story issue types. I manually added an Epic-Story Link type. But I hve no option to give it a 'style'. Does that come with some add-on? Or ... how do I add the style it wants?
