386 ISO vs AMD64 ISO images

Hi folks,

I am considering replacing my 2xAthalons with 2xOpterons.
That should be a plug in replacement of the appropriate hard
ware, the diskdrives and installed software should be good to
go.

Now, is there any advantage to installing clean from the
AMD64 ISO images?

I believe I should be able to change the CPUTYPE in the
make.conf file, move my kernel config to /usr/src/sys/amd64,
and rebuild as per the Makefile and have an 64 bit image, yes?

One thing I am uncertain about - how to I specify the
32 bit libraries are built? I will definitely need them for
the number of ports that are clueless regarding 64 bit.

Thanks,
Bruce

Okay. Is there a handy "migrating from i386 to AMD64"
FAQ you would recommend? I don't see anything right off
hand at the FreeBSD site...

Or am I good once I install the AMD64 ISO?

: FreeBSD-amd64 works the same as freebsd-i386.

If there were any switches I need to be aware of for
cvsup, etc. to get the AMD sources (well, same source,
different defines, I hope).

It sounds like I am good once I install the AMD64 ISO,
and since I have a disk for that purpose, it sounds like the
route to take.

I have subscribed to the mailing list, and I'll take
your word for how errr, "fun" it is to try what I was asking
about. :-)

Thanks!
