Configure the new gateway add the new gateway/trunk on cucm. Once ready move the pstn line to new gateway
Few commands like network clocking has some changes compared to the isr 2900

Hi,
nobody can give you a complete answer. That depends on which features, interface cards, ISDN connection yes/no, ... you are currently using on your 2951 router.
