Can't upgrade but can't wreck domain either

We have two domain controllers running w2k Advanced Server. We want to
'upgrade' these to w2003 server (not enterprise) and you CAN'T 'upgrade' as
it is not supported (only to w2003 Enterprise.

A = first domain controller with FSMO roles. B = second domain controller

I propose to:

1) run w2003 DomainPrep and ForestPrep
2) run DC promo on B and demote it, leaving all the FSMO roles on A
3) format the disk on B, install w2003 server and then DC promo on it to
make it a domain controller
4) move all the FSMO roles from A to B and run DCPromo to demote A. Then
blow it away and install w2003 and DCPromo it to be a dc.

Will this work?? Can anyone see anything wrong with my plan?

Hi Neal

That looks like it should work to me. Step 0 might be to take a backup so
you've got something to fall back on.

You might want to consider using new server names (even though this
shouldn't necessary). If you want to use the same server names, make sure
the computer accounts are removed and that there's no indication that
attempts at replication are occurring after you've done the demotions.

Kind regards

Thanks Mark.

The only step that really worries me is moving all the roles manually from
w2k to w2003 as I've never done that before. Any tips?

Oh yeah, one more thing, both servers are running DNS, so I'd like to make a
backup of that config so I can restore it easily. Never done that either,
is there a way to do that? Or is that something I can't do as it is part of
the AD structure?

NTBackup runs daily to back up the system state.

What DNS zone types are you using? AD Integrated will just replicate
between DC's. Remember to allow everything to replicate when you demote and
promote. You shouldn't need to worry about backing up DNS if Dynamic Update
is in place. Clients and servers will just register as they boot (or DHCP
will do it for the downlevel clients). All you really need to do if
something goes wrong with DNS is recreate the zones and point all the
clients and servers at the correct preferred DNS server. Aside from this,
set your forwarders and the rest takes care of itself. I'm not aware of a
tool that backs up the DNS config specifically.
