General :: Command To Copy Files Older Than <n> Days Keeping Dir Structure?

I'm trying to truncate a postfix Maildata directory for one of our users. I want to be able to move any files older than <n> days to a new location, but also copying the relevant directory structure. This should be doable in the one comman. I've used find to locate the files, and mv to move them, but I can't figure out how to build the directoryt structure on the fly in the new location.

This is what I have so far:

Code:
find /Maildata/editor -mtime +42 -type f -exec mv -v {} /EditorEmailOld/ ; > ~/editor.txt
