Switching between 2 xbox one systems

I have looked online and haven't really found anything and I am wondering if anyone here can help. Currently I have 2 xbox one systems in my house: one in the basement and one in the bedroom. Is there a way I can play a game like AC Valhalla in the basement, then go to my bedroom and continue playing the game where I left off? I know I would have to install the game on both systems but what about the save game? I don't know if this will transfer or not.

I can't answer for that game specifically, but I recently replaced the internal hard drive on my Xbox one and each game I reinstall has its saves and levels there. So I think they are kept somewhere in the cloud. If that's the case, I would think you could easily do it between systems.

According to This, if you're signed in to Xbox Live, your saves will automatically synced.

I have a similar situation (Xbox One in the TV room and also my bedroom). Xbox Live Cloud Saves means your saves should sync to any console automatically as long as you’re signed into the same gamer tag. It works well in every game I’ve tried, including backwards compatible 360 games.

I used to do this a lot when I had two Xbox One's. Yes, you just need to be logged into Xbox live and when you start up the game it will sync your game.
