Cisco 1721 to 1841 upgrade are the scripts compatible?

We have a CISCO 1721 router in our location whcih connects the dept to the the main office via VPN, the dept head purchased a 1841 Cisco router and now wants this to replace the existing router.

The current router works fine, are the configuration scrips compatible between both routers? Can I backup the scripts from one router to the other, is there any information available here whcih can be used as a guide to make these changes.

Thanks

Almost. You can use the same config, but the interfaces are numbered differently and you can simply edit the file to match the interface numbers. Also, don't forget to add "no shut" under the interfaces config.
Example:
1721:
 Interface Fast 0
  ip address x.x.x.x
 interface Serial 0

1800:
 interface Fast 0/0
  ip address x.x.x.x
  no shut
 interface Serial 0/0/0
  no shut

If I had an outside vendor make this change, how much time would such a change take and will any other equipment need to be programmed or will I just need to program the new router?

Thanks

It should take less than 30 minutes start to finish to replace the 1700 with the 1800.
If the 1800 is pre-configured the actual swap will take 5 minutes or less.
