Transferring previous portable version of Calibre to portableapps

I've been using the portable version of calibre from their website. I basically put it into the portableapps folder with all the other standard portable apps. Is there a way to "sync/transfer" this with the new portableapps version so that all version upgrades will be managed by portableapps from now on? I don't want to lose all my settings, plugins, list of ebooks, etc. Thanks.
