If you are moving and the phone system is going to be down, you will not be able to forward calls. You might want to contact the provider and ask them to point the main did number to the answering service number. They should be able to do that. I have had Cox do that for my pri customers during power outages or other times when the pbx is offline.

If the main did number rings to one phone only you can manually forward that phone to a speed dial number (the answering service)at night.
