I've uploaded the newest firmware for a 6921 phone I need to upgrade following the steps listed in the following link:
My question is regarding the next steps to get the phone switched over to that new firmware version. I'm not finding the right documentation that describes this. I would have expected it in a Release notes section of the Cisco software download page but it isn't there.
Am I supposed to simply delete the older firmware version in the TFPT management section of CUCM OS Admin page, or are there better instructions how to do this?
