Upgrade from BIG IP Edge 11.2.1 to 12.0

I am going to need to upgrade from 11.2.1 to 12.0 and I remember being told this was possible over the phone but I just wanted to verify. I have an active/standby pair that I am going to be upgrading and I want to make sure that I will be able to load the configuration ucs files from 11.2.1 into 12.0 when I upgrade on the appliances. I have been trying to search for articles but I have not been able to find any on F5's site.
