Theres an intermediate method between upgrading in place and doing a full re-install which si what I used when I did this. 1) Install amd64 onto a completely separate bootable drive (USB will do). On that one do a 'make buildworld', 'make buildkernel'. 2) Take down the machine you mant to upgrade - boot it off the USB drive. When booted off the USb drive mount the orignal '/' somewhere. 3) Do a 'make installkernel' and 'make installworld' with DESTDIR=/oldslah to install the 64 bit OS onto the old drive. I also rewrote the boot sectors on the old slash drive too. 4) Reboot - it should come up amd64 with the old config fine. I have done this a couple of time to convert from 32 to 64 bit installs. The beauty is that it preserves the config. I would note, however, that in my case I did de-install all the packages and re-installed them afterwards, so I was then running full 64 bit. but it works, and the machine is only down for a few minutes. -pete. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
