Cat 6500 upgrade

I have a 6509 currently running in Hybrid mode that I am researching to upgrade to native IOS.

On a regular switch, I can delete the old IOS image to make room in the flash for the new IOS image.

During the process I need to have the new IOS up on the switch. Do any of you know if it is a problem to delete the old catOS image (Then squeeze) then upload the IOS image during the process?

Hello Scott,

I would follow step by step the conversion procedure in the version for your sup/MSFC combination.

You can find it here:


For example for Sup2/MSFC2 it says to load the new native image on external flash slot0: see step 4 and 5

it says you can delete files and then squeeze files in bootflash: or slot0:

I'm not sure if this applies to catos image too that is your question.

Hope to help

Yeah, given the budget restraints, I was trying to avoid the cost of a memory card, but it looks like I'm going to need one. Getting a quote now.
