Hi guys!
Could you help me please?
I have some old request types that are no longer part of the customer portal, but they appear when an employee creates a ticket, as shown in the image below.

I tried to delete the old request types, but Jira gives me a warning because as they were used, there are several tickets that were opened with this type of request type and I don't know how to do this type of mass editing that the message informs me when I try delete the old request type.

What could I do? Is there any place where I can edit the request type that the employee uses when clicking Create, as I couldn't find it? Or do I really have to do mass editing to transfer these old tickets linked to the old request type to my new request type?
