Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Costs depend on area size, material thickness, and site preparation needs.

Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase.
