I realize this isn't a very helpful answer, but why would you want to do that? Copying will give you duplicate notes, and duplicate calendars.
If you want to move them, I would think a PC/Mac would be the way to go. Notes, for example, I can see in my IMAP client (Thunderbird) and can easily drag them from one Email account to another.
Not sure how you would go about moving a Google calendar to iCloud though. That might be a cut/paste proposition.
