When I did it, I believe I just made copies of /usr/lib and /usr/local/lib

running zfs so I made a snapshot of the 32-bit system as it was just before
the install. A 64-bit buildworld and GENERIC kernel both default to
enabling 32-bit support and compat libraries, and I believe a 64-bit kernel
will boot and run a 32-bit world, so compatibility is good.
Just be aware that binary file formats for programs installed via ports may
differ, so things like rrdtool datafiles and mysql databases will need to be
dumped to text form and reloaded. That's where the 32-bit snapshot came in
handy (so I had access to the 32-bit binaries after my port upgrades
finished and could dump using old binaries then reload using the new ones as
I discovered problems).
Thanks, this sounds very encouraging and I will try it.
Another question is: are there any parts that won't work in amd64,
besides file format issue that you just mentioned.
Like NVidia driver? MPlayer plugins (taken from Windows binaries)?
Linux flush in browsers, it's originally only 32-bit in Linux and works
through the series of hacks in nspluginwrapper?
