Since all you have it live rock, then yes I would remove it first just to make life easier!
Place it in a tub of some sort with water from your tank and a power head (a new clean trash can works well).
Once all the CC is removed, put the rock back in the tank THEN add your new sand around the base of the rocks. That way the rock is sitting on the tank bottom (more secure).
