Yes, my russian is rusty :-).
I have bitten the bullet and spend 3-4 days doing the migration. I
wrote the details here:
The page is written in Spanish, but the terminal transcriptions should
be useful for everybody.
In the process, maybe somebody finds this interesting too:
Sorry, Spanish only too.

Yes, the migration I did had plenty of safety points (you can go back if
something doesn't work) and, most of the time, the system was in a
state able to survive accidental reboot. Downtime was minimal, less than
an hour in total (several reboots to validate configurations before
proceeding). I am quite pleased of the eventless migration, but I
planned it quite carefully. Worried about hitting bugs in Solaris/ZFS,
though. But it was very smooth.
The machine is hosted remotely but yes, I have remote-KVM. I can't
boot from remote media, but I have an OpenIndiana release in the SSD,
with VirtualBox installed and the Solaris 10 Update 10 release ISO,
just in case :-).
The only "suspicious" thing is that I keep "swap" (32GB) and "dump"
(4GB) in the "data" zpool, instead in "system". Seems to work OK.
Crossing my fingers for the next Live Upgrade :-).
I have read your message after I migrated, but it was very
interesting. Thanks for taking the time to write it!.
Have a nice 2012.
