There isn't an upgrade path. You REPLACE your Front Ends and then you
create a new mailbox (back-end) server and move the mailboxes and
content to it.
The new Exchange 2007 CAS can be an FE to a 2003 mailbox
It doesn't matter what back end you're doing, be it SCC, CCR or
standalone with or without LCR, the CAS acting as the FE will work.
