You should not have to do anything really. Monitors named the same should not matter. All of the Outputs are assignable. So you can rename the Aux Bus and assign the "virtual" bus to the output that is connected to the monitor.
One thing to consider doing is documenting what everything is doing now. Setup a Camera that is shooting the panel if you can -- I would also Mic up the person so they can Talk through the effects and Custom Controls they are running. Build a 2 Box on and ME that would not normally be affected by these custom controls. Put the Camera shooting the panel in one and then put a Camera that is shooting the Set in another.
Run through all of your effects so that you can see what effect is doing what to which monitors and elements. Verbally document the names of the Effects and the Monitors. Then you can see which monitor is connected to which "Aux Bus" again note that the Aux Bus is just a virtual bus. It is not associated to a specific output. Any Output Can select any of the buses.
Now when you move you will have the ability to go back and figure out which Virtual Bus was being used for which monitor. Then when they tell you what monitor is connected to which physical output you can go into the Output Menu and change that output to be the AuxBus that the effects are using.
As for the CG wipes. I would hope that they will wire the physical inputs up to the board and use the same IP addresses. If not then on the input side not so bad -- in version 17 we added Patch Bay ability. So you can go in and tell the "Virtual" source to use a different Physical BNC. That way all of the Memories and Customs would still select the correct video. However in the case of the inputs (outputs are not as big of a deal to re-assign) I would "stress" to them that they connect everything back to the Input that they were on :)
IP addresses is another issue if they don't keep those the same -- you then have to change the device control assignments (Com Setup) so that they now point to the correct machine. Now for Timing of the wipes and control -- Unless they have some crazy change in Network latency this should have no impact on your effects.
