[Solved] Multiple Bungee Instances

Alright, since my last thread was a bust, I think this solution would be better. Alright, so I am creating a Bungeecord network that supports 1.6.4 - 1.7.9. The thing is, there is no Bungeecord that does that. So I am going to create a separate bungee instance for 1.6.4 users, and another bungee instance for 1.7.2 - 1.7.9 people. In order to link these together, I am assuming you need Round Robin. For this will you need 3 bungee instances or just two? And how do you check what client version...
