NT -> 2000 migration, is this thinking correct?

[Albion]

I have 4 servers

1) PII 400, 1gig RAM, PDC, NT 4.
2) PII 233, 512meg RAM, BDC, NT 4, Exchange 5.5
3) Dual P4 2.4gig, 1gig RAM, New Win2000 Server (Not on network yet)
4) P133, 128meg RAM, Linux DNS server with BIND 9.2.1

My plan.

1) Sync my NT 4 domain.
2) Take down machine 1
3) Promote machine 2 to PDC
4) Bring up machine 1 and demote to BDC
5) Upgrade Machine 1 to Win2000/Active Directory using machine 4 as the DNS server. (Yeah, I am going to use BIND. Why, because I like being controversial.

Step 5 is my problem. The system partition on this machine is only 2 gig with 500meg free. Will the 2000 upgrade clean out the old NT 4 stuff from the system directory? I'm not even sure if 500meg is enough to get the ball rolling. Is it possible to do the upgrade using the system partition as the upgrade point but using a separate partition for copying temporary upgrade files?

6) Add machine 3 to the new domain tree.
7) Promote machine 3 to the primary domain controller. (Is this even necessary?)
8) Transfer the file system from machine 1 to Machine 3.
9) Do a fresh Windows 2000 install on Machine 1.
10) Migrate Exchange 5.5 on machine 2 to Exchange 2000 on machine 1.
11) Do a fresh Windows 2000 install on Machine 2.

Is this a good plan? The only thing I am worried about is the disk space and RAID controller on machine 1. That, and the cross machine/OS version migration of Exchange. But my Exchange server is a simple install with 1 server and 25 users so it shouldn't be all that difficult.

Thanks for your time.

Welp it turns out the RAID Controller is not supported under Windows 2000. So it's impossible to upgrade that machine unless I can find a new RAID controller to thriow into it that fits in my budget.

i would recommend setting Windows 2000 root to the most reliable machine you have. Not necesarrily the oldest.
the windows 2000 machine that is not currently on the network would be a great choice and if you are set on upgrading then wipe that machine load NT4 on it promote it then take your other old PDC offline after they have synced. This should solve your raid issue as well
