First of all, create a backup of your current IOS (CatOS) image and startup-config.
Then make sure that enough space on flash memory.
Then look at this article "Upgrading Software Images on Catalyst 6000/6500 Series Switches"

Assuming that you're upgrading from one version of IOS to a later version.

I like to have backup copies of the existing IOS image and config on a TFTP server.

If you have enough flash, copy the new version to flash.
Put a "boot system flash:<ios filename>" command in the config.
Save the config and reload.

But read the release notes for the new IOS version first!!!  :-)

So basically i have to first copy the IOS image on the flash and then need to boot with the new IOS image.

do we need to seperately transfer the IOS for the Supervisior engine or SUP card.

Thanks

I am having the Native IOS 6509-E serios switch.

Correct.

I'm not sure I understand. But the new IOS image will need to be on the flash of the 6500.
