I'm about to replace one of my old 32-bit x86 Debian boxes with a

neede (which will be very minor).  So, while I'm at it, I'm curious --
is there any clean way to do an update that will simply replace all the
32 bit packages with 64 (and do all the other necessary multiarch
stuff)?

It depends.

Arguably the cleanest solution is to re-install using a 64-bit
installer. However, this will blow away your configuration, choice of
packages and so on.

If you want to cross-grade, the accepted procedure is detailed here:

I'm not actually doing anything with it that will require 64 bits; if
the answer is "no" I'll simply continue to run it as a 32 bit machine.

So, is it possible?

Thanks,

I'm using PCLOS for most Linux stuff, altho have tried some others.
PCLOS normally installs with a / and a /home partition. On one machine
I have PCLOS 32-bit and PCLOS 64-bit: they each have their own /
but they share /home.  This works quite well, altho there are a few
programs that don't cross over. Adobe Reader is one--there is no 64-bit
version of that. (I like Atril for a pdf reader on the 64-bit system.) I had the 32-bit system installed first, then added the 64-bit one when it came out. 
And I'm sure you know that no matter how many Linux distros you may be
multi-booting, you only need one swap partition.

Hope this helps.  --doug
