just configure the cisco router as it must be configured, connect it to your ISP and to your LAN and keep the non cisco router in the same rack.

in case cisco fails, replace it with the old rtr.

after the migration, you will find your cisco rtr connected to 2 ISP.

but if the cisco rtr fails, you will loose internet connectivity.

that's why, i recommand you duplicate your cisco rtr and you can use HSRP feature to insure automatic failover :when one rtr goes down, or its internet connection goes down, you will be redirected automatically to the second rtr. so internet connection will be more garanted.

hope this help
