I'm new to TFS administration. I got a request to remove 3 columns from the Kanban board for a TFS team project created using the Scrum project template. The columns they want removed are New, Approved and Committed. I thought I could click on the gear icon on the Work | Backlog Items | Board, but there was nothing I could do to the columns in the SETTINGS dialog.
So, I did a search and I'm found conflicting results. Some on SO claim that I need to run something named witadmin (?), which if I understand it correctly, will generate a XML file of the structure of those columns in the Kanban board. I would (if I understand it correctly) edit that XML removing the columns, then somehow run witadmin again to update it. But other responses say that's wrong. I'm not sure which to believe, much less where it is I go to run witadmin. Or is there another way to do this?
