Repurchasing Forza 5 on a New Xbox One

I previously owned forza 5 on a different xbox one, bought a bunch of the DLC pack and had unlocked a LOT of cars. I was always logged in with my xbox live account/profile in forza 5 and even did the Forza Rewards into that xbox live account.

Since then, I sold that xbox one and have repurchased a new xbox one since. If I were to buy a copy of Forza 5 again, would I be able to login to the same xbox live acct and have all of the same cars unlocked?
I understand I would still be able to download all of the DLC pack I had purchased, but would the cars I “earned”, unlocked and customized still be available? Or does that data only save locally on the xboxs? I don’t think it’s possible for me to get that save data from my old xbox.

Sorry if this has been asked before, I searched for awhile and couldn’t find an answer. I appreciate the help!

Thanks.

If you owned FM5 digital you don’t need to buy it again, because it’s linked to your account. Same with the DLCs.

If you had only the disc version, of course you need the game again. Disc or digital, doesn’t matter.

Your savegame should still be in the cloud, as long you didn’t delete it before.

Just log in with your old account on your new XB1 and launch the game.

When it says ‘sync with the server’ do NOT cancel. Sometimes it can take hours !

After that you can continue with your old savegame, rewards, etc.

When the ‘sync window’ doesn’t appear, your old savegame was deleted and you need to start from scratch …
