I experimented with migrating i386 to amd64 earlier this January. I used the official snapshots to do the main part of the transition, and that route is a timesaver in my book. Be sure to omit /boot, /etc, /root, and /var from the base distribution (base.txz). I ensured all ports were up-to-date before committing the transition to amd64. And I never messed with /usr/local/lib, since I instantly rebuilt all ports. Using ports-mgmt/portmaster is better than using ports-mgmt/portupgrade, at least until all ports are 64-bit native executables/libraries.

I am in the habit of setting up machines to use MBR, and have at least 2 of the resulting slices bootable. In a situation similar to yours, I had bootstrapped a new desktop to running stable/10 i386, and wanted to switch it to amd64 (while preserving the rest of the configuration). It was already set up so I could build world & kernel; I did that again, but issued "setenv TARGET_ARCH amd64" first. Once that completed, I mounted partitions 1 & 4 (a & d) from the "other slice" to a suitable mountpoint (e.g., /mnt), then: make installkernel DESTDIR=3D/mnt mergemaster -U -u 0022 -p -D /mnt rm -fr /mnt/usr/include.old mv -f /mnt/usr/include /mnt/usr/include.old rm -fr /mnt/usr/share/man make installworld DESTDIR=3D/mnt mergemaster -F -U -u 0022 -i -D /mnt make delete-old DESTDIR=3D/mnt I then rebooted from the "other slice"... and it came up running: FreeBSD 10.1-STABLE #127 r274634M/274637:1001502: Tue Nov 18 12:57:35 PST 2014 amd64 (I then used the procedure at the end of the portmaster man page to rebuild all ports, rebooted, and "cd /usr/src && make delete-old-libs".) That was back on 18 Nov, and the machine's been running without issues since. (I've been doing native source updates on it on Sundays recently, so it's now running FreeBSD 10.1-STABLE #129 r277317M/277317:1001506: Sun Jan 18 04:47:44 PST 2015 amd64.)
