I'm getting my 8+ on monday, upgrading from my 7. What's the best way to do this transfer? I kind of want to update my 8+ to 11 before putting my stuff on it.
Is it better to just start fresh? Or does restoring from an iCloud backup work really well? I just don't want to carry over any potential issues from my 7.
Restoring from iCloud is near-perfect. It restores all your settings like permissions, wallpaper, app placement, etc, and it starts downloading all the apps you have. The redownloaded apps will retain their data.
To be safe, you might want upload any game saves you have to iCloud if they support it.
Sometimes 2-factor authentication apps aren't happy after a restore, so if you use any, be sure you have their recovery keys handy. Also, it's rare, but if any apps you own aren't on the store anymore, they won't be restored.
If your phone does start getting funky for whatever reason, Reset All Settings (not Erase) is usually a good way to get it fresh without losing data.
