Is there a way to get a report/create a filter to show all issues that were in a specific project?

[Brianna Barnes]

I want to be able to track all the tickets that were once in our project, to be able to track everything that my team has been a part of. Since we have tickets that come to us and are moved away from us before being resolved.

Hello,

You can not do it out of the box. But you could use such plugins as JQL Search Extensions:

https://jqlsearchextensions.atlassian.net/wiki/spaces/SEARCH/pages/30497099/JQL+Reference+Server#JQLReference(Server)-movedIssues(projectKey)

Or JTricks:

Hello Brianna,

Unfortunately, History operators do not work for the field Project on JQL. It has been previously requested, however, our developers have decided not to pursue it:

- History searches do not support the 'project' field

That being said, The Assignee field is supported by history operators, so you can perform the following query to have the same information if the assignees only worked on your project's backlog:

assignee changed from ("user1", "user2")

Please, let me know if it helps.
