Rest API Get change history in all issue types in specific project

[Phil Borrell]

I  migrated a project from Jira Next-Gen to Jira Classic. When i migrated, all issuetypes became either Story or Sub-task.

I'm trying to use the REST API to search all issues in the Project that have ever been a different issue type.

I can do this for individual issues, but I would like to see all that were a Bug, or an Epic, and so on.

Does anyone know how to do this?

Hi @Phil Borrell 

You can try Issue History app from the atlassian marketplace. It let you view all changes were made with each issue list you need to analyze. Add-on lets you filter issues in different parameters: project, sprint, assignee, etc.  You can also use export and dive deeply into analyses (for example, with a pivot table in google spreadsheet).

Hope it will help

Hi @Phil Borrell ,

the only way possible way I can think of is the way you've described - search for all issues from your project, which were updated during some time period. And as a second step search through each of issue's changelog, if there's been an issue type change. 

As far as I know the information about issue type change is visible only in issue history and there is no endpoint to be able to do some bulk search on these records.
