Upgrade Cat6509 with highavailability enable

[lyesinn.ang]

Hi,

I have 2 Core Switches (Cat6509), each with 2 SupII module running highavailability.

I need to upgrade the CatOS of the Core Switches. Is there any procedure to follow or take note while doing the upgrade. Or is there any documentation on how to upgrade the CatOS running highavailability.

After upgrade of CatOS of the primary Sup, will the OS automatically sink to the Secondary Sup?

Thanks

LS Ang
