TFS 2010: Change 'Work Item' type from 'Product Backlog Item' to 'Task' - how to?

Question

I want to change the type of a 'Work Item' in TFS 2010: I entered a Work Item to the Product Backlog (we're using a Scrum template), and then I entered several 'Child' tasks, but I entered them as 'Product Backlog Items'. I should have entered them as 'Tasks'. How can I change them to appear as Tasks - children of the original 'Work Item'.

A previous question: Change TFS Work Item Type

would suggest that this is not simple. Can anyone help?

@PortageMonkey's answer to the question you quote contains pretty much what you need.

As noted you cannot directly change the work item type however there is a nice shortcut that may save you a lot of time for these scenarios. It will automatically copy links to change sets, test cases etc.

1. Right-click on your work item and select "Create Copy of Work Item"
2. The following dialog window will pop up where you can then change the work item type for the new item:
   
   Result: A new work item is created with the new type and the old one automatically added as a link and a comment added to the history area stating the work item ID it was copied from.

So, use this feature to copy them and convert them to tasks at the same time by choosing "task" in the copy dialog. Once the copy is done, flag the original item to "removed".
