Have half email accounts on Google Apps, and half on my cPanel server, same domain?

I have several email accounts on my domain, and I would like to migrate some email accounts to Google Apps. However, moving all the accounts would get really expensive, so I'd like to move only 3 email accounts to Google Apps, and keep the other email accounts on my cPanel server which is where all accounts are currently.

Is this possible? If yes, how can I do it?

Thanks
