Using both Networking systems in Unity?

Hello there,

With the new Unity matchmaking service, I thought it would be a pretty good idea to try and use it. What I am wondering is: Can I use the matchmaking connection that is using unet while keeping my gameplay multiplayer with the old system, can it run together at the same time? I am not really sure if it's really worth it to make all the effort to change all of my code for the new system, it's seems like a crazy daunting task so I would like, if possible, to keep my old code. I might change it later but for now I just want to use the Unity matchmaking service.

Thank you!
