How to find all duplicated Issue Type Schemes in Jira?

[Rumceisz]

Hi,

I just became a site-admin of a Jira. The instance administration was a complete mess: each time when a project was created, the former admins created a separate Issue Type Scheme.

Right now there are hundreds of Issue Type Schemes and plenty of them are similar but with different names of course.

For example: There are 6 Issue Type Schemes with exactly these Issue Types:

Story, Bug, Task, Sub-Task, CR

My question is: how can I find the exact similar Issue Type Schemes and delete the duplications? With that I could reduce the number of Issue Type Schemes by hundreds.

Thank you!

Hi @Rumceisz

Welcome to the Atlassian Community!

For Jira Data Center, Jira doesn't provide a built-in “find duplicate Issue Type Schemes” function. Jira DC exposes the Issue Type Scheme REST API, and you can retrieve the schemes together with their issue types using

GET /rest/api/2/issuetypescheme?expand=schemes.issueTypes

You can then compare the issue type IDs assigned to each scheme, sort those IDs, and group schemes that have the same set. This will quickly identify cases where, for example, six differently named schemes all contain the same Story, Bug, Task, Sub-task, and CR issue types. 

Another solution can be via ScriptRunner, I think. If you have it, let me know; I will try to create a script that will retrieve that duplication.

Hi,

Connect an ai to jira using either rest api or mcp and ask it to give you the name of issue type schemas with exact issue type configurations.
