Transfering tickets from other ticket program

[dirkteulings]

What is the correct way of importing tickets from another system?
We have tried it and we failed because of the:

UNFIXABLE ERROR: The issue with key XXX-166 has a null entry for the workflow step. (JRA-4714)

What is the correct way to fix this without cloning or changing issue types or even deleting those issues.

Is that even possible?

If not we should delete all the "broken" issue's and import them again, but this time correctly. Then the question becomes what is the correct way of doing this?

Although the DB migration is not suggested, you may still manage to inject your issue to a workspace. The key is to add proper records to OS_* tables.

There is an example code here;

!! But, you should be extra careful while playing with the DB, because so many things can go wrong, and you may broke your applications integrity.
