I don't have a new system, I would need to do it in place, on the same system.
I guess I should have clarified that I already have a 64 bit CPU, and 64 bit kernel, but my initial installation is 20 or more years old and has been updated since then, from that same initial installation. (It's even the same initial ext3 filesystem, since I used md raid to shift the installation to new hard disks over time, it used to be ext2, but that upgrade was automatic.)
Debian has the ability to have both 32 and 64 bit packages installed side-by-side.
I.e. they did the hard part. I just need some way to automatically shift each package to its 64 bit equivalent, then remove the 32 bit one, and eventually the libraries too once nothing depends on them.
