Cloud Saved Game Question

Hi. I recently gave my older brother my Xbox 360. Unfortunately it’s got my Forza Horizon save on it. I’ve been playing the backwards compatible version on my Xbox One but my original save must not have been synched with the cloud because I’ve had to start from scratch. If I get my brother to copy my saved game to the cloud from his house how do I then get that saved game to replace my current Xbox One saved game? When I log on to a new session it normally says syncing game with cloud, but would that load my 360 save or rewrite what my brother copied with my new save? Hope that made sense. I just don’t want to ask my brother to go through all of that, screw it up, and have to ask him again. He’s never been a gamer and I’m trying to get him into some games and don’t want to turn my gift to him into a headache, but I really would like to have that save to play. I’ve looked on the MS help for cloud saves but with what I am asking I’m still not clear on it.

Also, we’re all the cars I stored in my Car Club part of my save? I wouldn’t have thought so since they were available to everyone in the club, yet online my car club garage is always listed has having 0 cars in it, even though in single player, in the rare cases where the servers seem to synchronize for a second, it still has my car club listed next to my name.

Thanks for any help!

I’m going through the same thing… I have no idea what’s going on

I can’t figure out where any of the cars I owned on the 360 have gone. I’ve also transferred my save to the cloud but cars are missing (even after downloading all of my DLC packs through the xbox one dashboard by managing the game).

mine are in the garage like normal. maybe restart DLC downloads.

it should work just fine.

i downloaded horizon, started the game and was surprised to be starting over, so i deleted everything off the xb1.
started up horizon on the 360 and everything was there. went to the 360 storage and moved the entire horizon game save to “Cloud”.
Cloud upload and sync took about 5 or so minutes on the 360.
started up horizon on the XB1 and it found my horizon game save, asked me if i wanted to use it, click yes. took several minutes to download and sync.
restart horizon game and everything was there.
