This change will be done remotely. What would be the best way of doing this change so as not loose connectivty to the switch.
A new router 2921 has been configured and sent to the site replacing the current 1841 router.
Also there is only static routing to the site for 10.0.16.x/24 and 10.200.16.x/24
The default gateway on the switch is going to change and the only current Vlan interface is going to be shutdown.

copy the new config to startup and then reload

[TRIE]

Thanks Markin.
Assuming this is to export running-config to tftp, make changes, then copying it over as startup-config?

[TRIE]

Something like this?

• copy tftp:[[[//location]/directory]/filename] nvram:startup-config
• copy tftp:[[[//location]/directory]/filename] flash[n]:/directory/startup-config

[MarkinManchester]

Yes thats it, since you dont have out of band be careful and test your configs before sending them to remote devices. Just remember to work from the edge and then inwards.

Always make sure you have a guy locally just in case it all goes wrong, also save the previous config to nvram in case you need to regress

Also "reload in" can be your friend sometimes
