I need to upgrade the IOS on a catalyst 6509 running integrated IOS.
The current image is stored in sup-bootflash. I like to have this image available if the reload with the new IOS should fail.
QUESTION: Will the 6509 boot on the new IOS if it is placed in bootflash and I code
boot system flash bootflash:new-IOS
boot system flash sup-bootflash:old-IOS
gwone4#sh file sys
Size(b) Free(b) Type Flags Prefixes
65536000 25572008 flash rw sup-bootflash:
65536000 65536000 flash rw bootflash:
Yes, as Greg says, as long as you have the space you should be fine.
In short, Yes.
It is always a good idea to keep your previous IOS available, in flash if possible, but tftp or other means if no flash avaialable.
As long as you have enough free space for the image, as it looks like you do, you can load the IOS to the flash/bootflash and create your boot system commands to point to the new IOS, in the order you require.
