If the equipment gets moved from one location to another, I do not believe that all processes have to be revalidated. The reason the quality team argued that is because if the equipment was assembled in a different location, this might lead to error due to improper setup or a setup in a completely different environment (percent humidity, temperature, etc.). The most important aspect is making sure the equipment is producing the exact same results in every location and making sure the test method that was developed is being followed appropriately.
