I have been facing the problem about Technician Group, When I changed the technician from group A to group B, the technician can't view thier old tickets on group A because these tickets can view by technician from group A only. This problem can solve by manually edit group from edit request page.

However, I have a large information to correct and I can't manually correct them. Do you have any batch or tool for update a large information like this case?

Best regards,
