<OUTPUT TRUNCATED>
To perform a file transfer in a Cisco ASR920, use the copy nvram:startup-config <ftp/tftp://<REMOTE IP> command. Make sure the source interface can reach the remote file server.
ASR920#ping 172.27.5.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.27.5.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 196/196/196 ms
ASR920(config)#ip tftp source-interface Loopback0
ASR920(config)#end
ASR920#copy nvram:startup-config tftp://172.27.5.3
Address or name of remote host [172.27.5.3]?
Destination filename [startup-confg]?

I renamed the file to startup-config2 (to avoid any file conflict), transferred it to the new Cisco ASR920, boot the new config using copy nvram:startup-config2 running-config and issued write memory to save config. Booting the new startup-config to running-config only took a few seconds.
This greatly speeds up staging a new router (in this case RMA replacement). It also lessens the human error if you have a big configuration file.
