We're currently using a "teams based" project and there huge limitations. We need to move to a "company managed" project instead.
I'd like to first do a copy of all the issues, check to make sure everything works fine and then do a final migration.
However, the bulk edit feature only allows you to edit 1,000 items at a time. There is a warning that tells you that we will lose dependencies, links, parent/child relationships. I don't want to lose those relationships and it would be hugely troublesome to rebuild that.
I haven't been able to find an answer on how to move all 5000+ issues, their links, dependencies, attachments, assignees, etc. to a new company managed project.
Help!
