can i use unity3 side by side with unity2 both pro licensed?

pretty much question is in the title…anybody knows?

Yes, a Unity 3 Pro license applies to all previous versions (or at least Unity 2; haven’t actually tried it with Unity 1).

i have unity2.6 already licensed, i want to install unity3, just to use different folder then and the same serial and everything will be fine? dont want to mess something up!

i just want to try unity3 maybe start a new project with it, and want to continue working on the current one using unity2.6, is it possible on the same computer? that is all i want to know
