With some delay, I finally got around to trying this. It appears that 
things have worked out fine, as per your instructions above. The 
migrated server has been running for 5 days now on a live setup of an AD 
DC and 10 workstations - and everything appears ok. So I guess the 
answer is that, indeed, it is possible to change the domain name during 
the classicupgrade. Thank you for the pointers.
