Add fields to existing TFS Work Items?

Question

I need to add some fields to my work item types in an existing team project to support integration with other toolsets. However, after adding those fields in my work item type definitions using the Team Foundation Power Tools Process Editor, and following the instructions detailed here, the tickets still do not contain this field. Instead, it is only new tickets that are created with this field.

Is it possible to add a field to existing TFS work items, rather than just updating the Work Item Type Definition for future work items?

We're using Visual Studio 2012 and Tfs 2012.

Answer 1

It seems as if this question is invalid; upon adding the field, the existing work items are indeed updated with the new field. However, a restart of visual studio is required in order to see the field on existing tickets, while new tickets have the field visible immediately. This can cause confusion about the state of the system for the user (me).
