just back up to external, your saves. if you're not activated, activate with account activator. then, use it again after you upgrade to get your saves back. no need to use save mounter since it's the same account, so it's very easy.

do that immediately after you change drives, because there's an issue with using a different account with installing games. if the account is not detected, games will crash. this is just an easier way of doing what you plan to do without having to make a full backup. I don't think trophies are included just like with the ps3, but @Leeful has a trophy backup and restore payload as long as it's the same account and system.
