If you are talking about going from 6.x to 7.x then you should, but you
can probably get away without doing it.

If you are talking about going from i386 6.x to amd64 7.x, and you have
to ask, you should be doing a clean FreeBSD install.

Hi Paul,

If you change from 6.X to 7.0-RELEASE, then ``yes, that's a good idea''.

If you change from 32-bit 6.X to 64-bit 7.0-RELEASE, you will _have_ to
rebuild your ports as 64-bit applications.  Any subsequent port builds
will be built as 64-bit applications, so if you keep the 32-bit versions
around you will end up with a very odd mix of 32-bit and 64-bit parts.
That's bound to cause a lot of grief in the long run...

NOTE: If you rebuild FreeBSD 7.0 as a i386 (32-bit) system, it's
probably going to be a good idea to start from the packages in the
release CD-ROMs and then only rebuild the stuff that *really* *REALLY*
needs rebuilding.  A couple of very good reasons to rebuild a subset of
your ports are:

  * You need non-default options when building some ports.

  * Important security fixes in one of the installed ports.

A good indication of when to rebuild ports/packages to fix security
issues may be provided by the `ports-mgmt/portaudit' utility.  The
output of running `portaudit' looks like this:

: [EMAIL PROTECTED]:/root# portaudit -Fa
: auditfile.tbz 100% of   49 kB 9279  Bps
: New database installed.
: Affected package: fetchmail-6.3.8_6
: Type of problem: fetchmail -- potential crash in -v -v verbose mode (revised 
patch).
: Reference: 

:
: 1 problem(s) in your installed packages found.
:
: You are advised to update or deinstall the affected package(s) immediately.
: [EMAIL PROTECTED]:/root#

This sort of output from `portaudit' means I can keep using my installed
ports, after rebuilding only the `mail/fetchmail' utility (and any ports
that depend on it).

I have a dual core Intel server running 6.1 RELEASE i386.  I want to
update it to 7.0 RELEASE.  Can I also switch to the AMD release at the

AMD64 is for 64-bit chips from AMD and Intel. whether it is multi-core
is beside. run i386 still if you want/need 32-bit operating system.
there are some features and programs that will NOT work with AMD64.



Thanks, Sean.  Maybe I'll understand FreeBSD some day.  :-)

Will I need to rebuild all my ports after compiling the kernel and world?

AMD64 is for 64-bit chips from AMD and Intel. whether it is multi-core is 
beside.
run i386 still if you want/need 32-bit operating system. there are some 
features and programs that will NOT work with AMD64.
