I'm doing an evaluation of JIRA OnDemand at the moment.
I've imported the list of issues from the issue tracker of one of my Bitbucket repositories, and it mostly seems to have worked.
The one strange outcome I've noticed so far is that the ordering of the new issue keys doesn't track with the ordering of the issue numbers from the Bitbucket issue tracker.
That is, Bitbucket's #2 is now XYZ-3 in JIRA, #3 is XYZ-8, #4 is XYZ-7, and so on in random fashion.
The Bitbucket issue numbers came over correctly in the "External Issue ID" field, but is there a way to cause them to be the numbers of the corresponding issue key?
I'm more than a little surprised that this isn't the default behavior.
