Help upgrading Cisco 1841 IOS

[petersonja]

We're going to be replacing an 1841 router this afternoon, but RMA 1841 router will need to have it's IOS upgraded. Need to figure out how to configure the old cisco router to be able to copy the IOS to the new cisco router across the LAN. Any information would be great. Thanks.

I will be doing this over the console port and an OOB modem, or else it wouldn't be as difficult.

I would bring the new router up on the network with the IOS that shipped with it.  TFTP the new IOS to the new router. Change the boot statement on the router, and reload.

Hello,

In addition to excellent advice from Christopher, I would like to add a link here, about Cisco 1841 IOS upgrade procedure:

Just in case that you need help how to implement what Christopher suggested.
