I've set up a JIRA OnDemand instance, and went ahead and created some projects there and got them filled in and scheduled.
Now, I want to migrate the rest of my data from a hosted/standalone JIRA instance into OnDemand, in addition to what's already in the OnDemand instance. When I used the importer tool, it indicated that configuration would be reset, attachments deleted, and issues cleared.
Is there any way to append a bunch of tickets, attachments, and comments to an OnDemand instance? Like the project importer for standalone?
