If I delete a cloned project in JIRA, will the original project be affected in any way?

[Blerta Koxha]

I created a new project and cloned the backlog from another project. Now, I have the old project's current iteration in the new project. I want to delete the new project and not transfer/clone until the old project is completed. Can I delete the new project without it affecting the original project?

Yes and no.

Projects are totally separate entities and contain separate issues.  If you create and use projects A and B, so they've both got a pile of issues, and then you delete project A, all of A's issues will be deleted, but nothing will happen to B at all.

Except:

• Any issue links from A into B will be deleted, because one end of the link has gone
• You say "cloned backlog" - I am not sure what that means.  Have you cloned all the issues in A's backlog so that there are completely separate issues duplicating them, and then moved those issues into project B?  Or is the cloning something else?
