Okay, I'm doing that now (it will take a while, system is on IP-KVM and
needs to get a CD-ROM attached to it).

In the meantime, here are a few other questions that are not entirely
obvious to me:

1. The system currently runs x86 FreeBSD 6.0. In the process of switching
to AMD64 6.1, will I need to recompile everything (apache/etc) or will
this work okay with x86 32-bit binaries?

Yes, the 64bit system has support for running 32bit apps, I just ran a quick
test and built a test program on x86, tried linking both static and dynamic,
and both worked on an amd64 install.

2. Are there any changes to the filesystem structure or can this switch be
done "in place" without reformatting the filesystems?

Filesystem is not architecture specific, so should have no problem with the
switch.

Sorry if these questions seem pedantic, I've never done a move from x86 to
amd64.

Not pedantic at all, just normal good questions :) Good luck in your switch :)

Jack
