I couldn't open the files- I'm still on 2009. As I understand your question, you are trying to 're-locate' the counterbore to another face and the feature was created using Hole Wizard.
-collapse the Cbore feature in your feature tree (click the '+' sign next to the feature)
-right click the 3D sketch under that feature and select the edit sketch icon
-once in edit mode, click the 'point' and you'll see a small relation icon. Delete the relation (not the point) from either the keyboard or the relations listbox on the left (should read 'On PlaneX')
-Now you are free to select the point and another feature to create a new relation, in your case, another plane. Select the point you just 'unconstrained', Ctrl. select the new plane you want the counterbore on and apply the On Plane constraint
-Rinse and repeat for all other cbores.
You may have to add locating dimension constraints in order to match the hole locations on the mating part.
