This seems like it ought to be straightforward but somehow I cannot get there.
Created new issue type called CR (for Change Request).
Created issue type scheme called Change Request, and it has a sub-task too.
On Issue type schemes page, three dots, associate. Selected the main project which has other issue types of course. Selected "associate". Then, I am viewing step 1 of 8 to MIGRATE other issues now into this CR and Subtask scheme. So, hit cancel.
Searched for answers, not finding any, hope you can help.
Thank you!!!
