If code allows, yes.

Cut up the existing rubber before installing the new insulation. Or else you will have a double vapor barrier situation.

so glad you mentioned double-vapor barrier in your post Grumps.

We usually just cut out the field membrane and leave the seams just to make sure there are no adverse effects.
