Do I have to regenerate license keys for this upgrade? Basically I am upgrading UCCE from 7.1(5) to 7.2(6) and I am trying to figure out to do with CAD and CTIOS. I definatly want CTIOS at 7.2(6) if I can keep it there. Do I need to upgrade my CAD and if so what is required from a license perspective. Also will the auto update function of the CAD client work in this scenario? Thanks!
