Well, I know this is an old thread but did you ever find out? Mine expired and everything stopped working. Couldn't push any settings or update device info. I got a button dialog on the profile in Settings saying "This profile has expired. Update this profile for a newver version. [Update Profile]" - which didn't work. I ultimately re-enrolled, but I could imagine it being a nightmare to re-enroll a large number of devices.
