2600 dual t1 reconfig

Here is the situation:  
we have two T1's on our 2600 router.  We just got our fatpipe Warp device (combines two connections).  What do i have to do to this router config to decomission the T1 on Serial0/0?  I am kind of confused about it all so i ask you the experts to show me the fastest and most efficient way to do this.  when i do make these sweeping changes to the devices i need as little downtime as possible.

more info on the t1 we are removing:
ip address 207.250.123.150 255.255.255.252
ip route 0.0.0.0 0.0.0.0 207.250.123.149
assigned lan netblock: 64.132.65.224/28
lan fast ethernet: 64.132.65.225 255.255.255.240
lan ethernet usable ip's: 64.132.65.226-238

The router I am moving this t1 to is already setup and i have tested it successfully.

The absolute simplest way to "decomission" a serial link is to simply shut the interface

  router(config)#interface serial 0/0
  router(config-if)#shut

The static route will automagically disappear (not from the config, but from the route table) as soon as you shutdown the interface. This puts in "administratively down" mode, but the configuration and everything is still there in case you need to bring it back up (simple "no shut") in a hurry.

Once you get everything working the way you want, then simply remove the static route entry
  no ip route 0.0.0.0 0.0.0.0 207.250.123.149

so to shut down the interface just
enable
int ser0/0
