@gjr26 Both accounts must be active in order to transfer your phone number, so if you intend to transfer I would do it before the last day of your current service to give time in case there's a delay. Definitely don't cancel your current provider until you are sure the number has transferred over, it will happen automatically during the switch. If your current provider's account is post paid you might want to check if they give a pro-rated refund for days not used after porting out (unlike Public Mobile which is prepaid and does not).
