Update of Adddress in Equipment master

Hi All-

We have an requirement where we move our serialized equipments from one customer location to other customer location, we use the address sub tab( in Location tab) to maintain the physical address of the equipment master.

Say we had the instrument at customer site for one year, thus having year worth service history at that location.

Now once we move the instrument from one location to other location we have to update the address to reflect the latest address for the instrument so we update the address.By doing so the system is updating the historical service notifications and service orders with the new address which is an issue for us from compliance propspective.

What do we need to do so that the historical notifications and service orders are not updated even if we update the address of the equipment.

Thanks for the help in advance.
