It says that it will overwrite my save but doesn't mention NG+. I might try some trickery with save backups and see what happens with it.
Edit: Yeah, no NG+ stuff when starting a new game.
I have a question slightly related with this.
I've been wanting to replay XC2 (most specifically, the NG+) for a long time now, but I haven't because I don't want to lose my original save (yes, I know all the relevant stuff and even the play time is transferred, etc. but my OCD is too strong). Do you guys know whether it's possible to "fork" my cloud backup using a secondary console?
What I'm thinking about is the following:
1) Logging into my profile in my bf's Switch.
2) Downloading my cloud backup there.
3) Disabling the automatic cloud save synchronisation in my profile in this (secondary) Switch.
4) Starting the NG+ in my console.
Ideally, if this works fine, my original save would remain isolated and safe in my bf's console. However, I'm not sure whether disabling the automatic cloud saves in my profile in the secondary console would also affect my primary console. Has anyone else tinkered with this before?
Thanks for the help!
