Upgrade Sup vs-s720 10G 3c from 12 to 15 version 2 supervisor per chassis

[Bhaseeth Ali]

Need to upgrade Sup vs-s720 10G 3c from 12 IOS to 15 IOS version.

We have 6513 switch with 2 no's of 720 Sup's in one chassis.

can some one tell step by step procedures for upgrade the same withs cmd's.

I got the version 15  Frimware from cisco site.

Previous image Currently active is an is an modular image with file name s72033-ipservices_wan-mz. at the end

The new image does not contain the word wan in the image file name

The new image does not contain the word wan in the image file name

That is fine.  New images are not modular anyway.

As for upgrade, you can do this in 2 ways.  One would be to load the new image into both sups, change the boot variable, save and reboot the chassis.

The second way to this is if your sups are in SSO redundant mode, you can upgrade the backup sup first, reboot it and than force a fail over from the primary to backup and than upgrade the primary.  Both procedures should be done in a maintenance window.
