Will I be able I continue to upgrade a multi-DC environment going forward, or might there be a point where I run into issues?

I realize you don't know what upgrades are going to be like in the future, so I guess intent is the point of the question. We are bleeding edge and running Samba 4 beta in production, so I'm just trying to be as cautious as I can in a beta environment.
