I have 2851 router running 12.4(4)XC6, I want to upgrde to 12.4-24.T2. I have both images on my router's flash I removed the old boot system flash command and created a new one; "boot system flash c2800nm-adventerprisek9-mz.124-24.T2.bin". When I reboot the router will always return to the 12.4(4)XC6 image. I'd rather not remove the old code as this is a remote site and it will be a huge problem to get the router restored. The confreg is set to 0x2102. Is there a way to force the router to boot to the new image? Thanks in advance!
Directory of flash:/
1 -rw- 39715748 Jan 18 2010 10:12:12 -05:00 c2800nm-adventerprisek9-mz.124-4.XC6.bin 2 -rw- 59455672 Jan 18 2010 15:05:24 -05:00 c2800nm-adventerprisek9-mz.124-24.T2.bin
Try "boot system flash:c2800nm-adventerprisek9-mz.124-24.T2.bin" OR copy the old IOS to your TFTP, delete the old IOS from the CF and copy the old IOS back. Make sure the IOS is found BELOW the new IOS.
Just did a quick test in my lab routers, and I am able to boot it off the new image while leave the old image in the flash. Here is the show output
