Thank you very much for giving these examples. Sounds really nice. Have 
not tried it yet however.
Still feel it's a pity FreeBSD did not incorporate the creation and 
managing of BE's within the system.

You can even upgrade a new environment while you continue working with 
the current one with

   manageBE create -n  -s  -p 
   manageBE freebsd-upgrade -n  -p  -r 
   manageBE activate -n  -p 

Then reboot into the new BE and complete the upgrade with the 
final "freebsd-update install" step. But I needed to 
change "chroot /${bootfs}" near the end of the script 
to "chroot /${pool}/ROOT/${bootfs}" to get "manageBE freebsd-upgrade" 
command to work.

Along similar lines, if you need to do a massive ports upgrade which you 
suspect might go pear shaped then you can do it in a new BE without 
upsetting your working system:

   chroot /tank/ROOT/newBE mount -t devfs devfs /dev
   chroot /tank/ROOT/newBE portmaster -a
   chroot /tank/ROOT/newBE umount /dev

... then, if all went well,  activate the new BE and reboot.

Have you considerd using manageBE
? With
this tool you can set up cloned alternative Boot-Environments (BE) so
that you can go back to your old BE if the new one doesn't work.

I'm in the process of upgrading to 9.0 and taking the opportunity of 
changing over to ZFS. I needed to re-arrange my filesystem structure to 
boot from tank/ROOT/someBEname/ instead of tank/ (and make sure the 
mountpoints of any descendent file systems are suitably adjusted) but 
it was worth the effort.

I installed 9.0-RC2 from the ISO onto a spare drive so I haven't done an 
8 to 9 binary upgrade but I have used freebsd-update to upgrade from 
9.0-RC2 to 9.0-RELEASE and that went through without any problems.

I will use the binary upgrade path. It seems easier for a non high-tech 
system ;-)

I did last week a source upgrade and the new generic kernel has not able
to detected my hard disks anymore and therefor the system could not be
booted, because the zfs file system was not mountable anymore.

But if some users are reporting here good results, I maybe will try it
again.

My main problem lies with the installed ports. I know the -all- have to be
recompiled, but I don't know an easy way for this job.  I always use
portmaster. Do I have to make a list manually for all installed ports? Or
is there a procedure to follow in this matter? I'd like to get some

It works great with source upgrade, so freebsd-update should not be a
problem but i haven't used it yet to upgrade to 9.
It is used like this: freebsd-update -r 9.0-RELEASE upgrade  (i.e. not fetch)
See also the handbook for a good explanation

You can use portmaster --list-origins to make a list of all root and leaf
ports and use this to reinstall all ports after the upgrade.
See man portmaster for a good example.

Or you can use portmaster -af to recompile all ports.
Ah, yes, I remember the latter is disadviced because some ports can have 
differences so you have some garbage if you run portmaster -af
I will look up the example in the manual. It also will tell me 
(probably) if all ports have to be removed beforehand or that this does 
not matter.

Not "have to", but it's often considered
"best practice". If you don't want to
recompile all your ports, make sure two
things are met:

1. You have COMPAT_FREEBSD8 in your kernel.

2. You have compat8x-i386-8.2.12345.67890
   installed (or amd64 respectively).

This will work as long as you're not starting
to install something new (which may cause
library version trouble).

However, using a port management tool to do
the job of "update all ports" is often highly
recommended.



> I always use

Did you look into its manual already? :-)



> Do I have to make a list manually for all installed ports? 

Depends. A possible approach is that you make
a list of your "primary ports", i. e. the stuff
that you are _really_ intending to use, where
"secondary ports" they depend on (i. e. the
dependencies) are not mentioned, as they will
be installed anyway. So for example, if "firefox"
is on your list as you intend to use it, there's
no need to list all its dependencies as well
because they are implicit.

Sure. See "man portmaster", section EXAMPLES,
where you'll find "Using portmaster to do a
complete reinstallation of all your ports"
with a complete procedure.
