Hi,
I'm trying to replace Application A with Application B but allow the user to chose when this happens (using Install and Available as deployment options). If I set supersedence rules then App A automatically gets uninstalled and App B installed. I've seen the option 'automatically upgrade any superseded versions of this application' but this is greyed out when deploying to device collections (although it can be configured when deploying to user based collections). Why is this option greyed out - is there any way to select this (if not, why would Microsoft put it there?). I have seen that this is by design but I'm not sure why you wouldn't allow the a user to upgrade when they choose. I guess a way round it is to set a deadline for a not later date but this isn't a clean solution.
Thanks.
