can you reposition footage and it's motion path without disturbing the positional keyframes.

or do you just move the footage and re-do the keyframes.

The easiest way would be to parent your layer to a null, and then move the null. Your relative motion path for the original layer will remain unchanged when you move around the null object.

The null plan is the best one. But just to show that there is more than one way to skin a cat:
With your current time indicator on a position keyframe, you can click on the position property to select all the position keyframes and then scrub the position values. All the keyframes will adjust.
A third way:
Change the anchor point's position.

[Michael Szalapski] "...there is more than one way to skin a cat:"

....and here's yet another way to skin this particular cat. Do like Michael says: put the timeline cursor on a keyframe & highlight the position property. Now use the arrow keys to move the layer. The entire motion path moves as you hit the keys. Works with the x10 keystroke combo, too.

You could also add a couple slider effects to your layer and put an expression on the position with the two sliders as variables then add those variables to the x and y positions. (Add another slider for z position.
