Hi,
We are upgrading our core 4507R+E switch with 2 sup 7L-E from version 3.5.3E to 3.6.5E
we copied the new ios to both bootflash and slave bootflash . and we didn't delete the old ios
We configure the boot command to boot from the new ios but it fail
ROMMON version is 15.0(1r)SG10
Config register is 0x2102
We think now to delete the old ios and test with the new ios only on flash
Please help if it is ok or there is a better method. also do we need to upgrade ROMMON version to latest 15.0(1r)SG14 ? but 3.6.5 isn't latest [it is the cisco suggested one]
Thanks
