I've always had great experiences upgrading Android devices. Once I log in for the first time they sync wifi and applications pretty seamlessly.

My wife recently picked up an S4 and none of her things synchronized. I was pretty surprised at the time but thinking about it later I realized the AT&T clerk skipped the initial sign-in process. It looks like the option to sync old apps/passwords is only available upon launching a fresh device (which being a Nexus user no clerk ever bypasses setup on my devices).

Anyway, this might be why your phone isn't syncing? I'd be interested in seeing some option to force sync Android devices with backed up data at any time.
