You shouldn't be making redirects if you want to keep your old pages indexed and their rank.
I do this all the time, especially to fix canonical issues, and Google usually has little problem following the old page to the preferred location and maintaining the page rank.
However, nothing else has changed on the page, everything remains the same so it's easy for Google to detect it's a simple move.
What the OP did was a wholesale site renovation, basically what a new owner of the domain might have done, totally different issue than a simple URL redirect.
