Remote router upgrade with two images in flash via tftp Danger Dog 08-18-2004

I need to perform a remote IOS upgrade on a Cisco 2600 series
router. Normally I have the router sitting on my desk when I do the
upgrade, but this time the router is a thousand miles away. I'm
assuming I can tftp the image to flash with a new file name and it
will save both images as long as I tell it not to format the flash.
Am I correct?
Also I need to tell the router to reboot and use the new image. I'm
assuming I can use the boot command to point to the new image. Do I
also need to give the router the path to the image in the flash
memory?

Thanks.

TFTP the new file into flash, assuming you have enough flash for both
images. Once the file is copied, do:

router(config)#boot system flash <new-file>

Reboot.

Check this link if you need more info.
