Cisco IOS - 6509 to Cisco 6509-E

When I need to swap out a chassis, I do a pre-capture before the move and compare these show outputs after the move. Some commands that I run are below and every migration will be different depending on what protocols/services are running within your environment. This geared towards my setup. Another useful options is to copy the running config to disk0: and if there is a second sup, sup-slavedisk0:.  One command that I have found very useful during these times is configure replace disk0:running-config.

When the configure replace command is entered, the current running configuration is compared with the specified replacement configuration and a set of diffs is generated. The algorithm used to compare the two files is the same as that employed by the show archive config differences command. The resulting diffs are then applied by the Cisco IOS parser to achieve the replacement configuration state. Only the diffs are applied, avoiding potential service disruption from reapplying configuration commands that already exist in the current running configuration. Taken from Cisco.
