save the running config to the nvram by giving copy runn startup
This you have to do before power down the router. You should not swap the cards when the router is up and running. 1721 doesnt support hot swap , so power off and then replace the wic and again power on....
Do a backup of IOS (if not done already) and config on a tftp server (you might need it at a later time).
Then power off the router. Swap cards. Boot up the router. During boot up the router will find the new card and will configure any interface in the shutdown state. Once the boot process will start the router will attempt to configure the old card but it will not be able to find it (you might notice the errors if you observe the boot from console).
Now configure the new interface(s) save the config with "copy run start" and back it up with "copy run tftp".
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
