Can I switch my Metro PCS number to my new Verizon iPhone?

I just purchased a iPhone 4S (Company is Verizon) Is there any way I can make my old metro PCS number my number for Verizon?

Why don't you ask the carriers themselves.

You can port, but only if your Metro PCS account is active. If that account is not active any more, sorry but you are out of luck, your Metro PCS number is gone.
