In my old project (old project key SJT) I have some deleted issues and there was issue key sequence like this: SJT-1, SJT-2, SJT-4, SJT-5, SJT-7.
I want to migrate project and in a new project (new project key KLM) when I will import issues, issue keys have the following sequence: KLM-1, KLM-2, KLM-4, KLM-5, KLM-7.
Can I do it or issue key is not possible "adaptation"?
