Hi,
Here is a link on how to upgrade the 6500 image. Cisco TAC usually does not approve or disapprove an image, as they don't want to be responsible if something happens to your device after the upgrade. They can however guide you in selection an image and can be on call during the upgrade, if you have support contract on the device.
