Have you tried something git based? That way the tickets, etc, exist on your machine and there's no real risk of being de-platformed. Whilst not an actual answer to your question, I thought it might be a good direction for you to look into. Also, I've seen Redbooth (formerly Teambox) we'll recommended and since it's OSS it can be self hosted pretty easily.
