Is it neccessary to maintain the docking ports of the ISS?

Inspection, cleaning, lubrication, replacement of worn out parts like O-ring seals?

Where are the seals, on both sides or only at the side of the docking space ships? If there are no O-rings at the ISS side, you don't need to replace them.
