The problem is pretty obvious;
- We have several hundreds of tickets under a project ...
- ... where some of them are already closed, some not yet started and some in progress ...
- ... and we want to move these tickets under another project ...
- ... which will break the links on Bitbucket PRs hence break the reverse links on Jira tickets.
It might be easy to simply update the PRs but since already merged PRs cannot be edited and they are already linked, what other options do we have to keep the links between Bitbucket and Jira?
