    I have a replacement box with two 2TB drives.

    How do I best clone the old machine to the new, with minimal (or better,
    no) downtime, being able to wind up with double the drive space on the new

If minimizing downtime is your objective, then I would recommending
doing a fresh install on the replacement system and rsyncing everything
over.  That lets you have the old system up and running until the very
last moment.

+1 for a file server.

If it's a workstation, put all the drives in the fastest box, mount both RAID's, and then rsync.
