I have been preparing and testing the import of existing issues held in another application into Jira. Last Thursday I was able to import a group of Epics with Name and Summary and create these in Jira. I the then mapped the corresponding field from my source data to the Epic Name. This worked and all the data was pulled into the Jira issues including the Epic Name the issues was linked to.
I had some other tweaks that I needed to do to the data to optimise the import and used the same configuration file with a couple of edits unrelated to the Epic name and when did another import test yesterday the Epic names did not populate. I have no idea why!
I am hoping someone can help me solve this puzzle.
Thanks,
