We were in fact planning on doing it as you recommend, 2008 member servers
to DC's, then demote the existing 2000 DC's. I wish we could throw in a
test version of all our app/dev servers into a fully parallel environment
but we lack the equipment resources to get the to make it possible. We
intend to space the schema extensions and any "prep" commands at least a
week apart, taking backups all the while, such that sufficient time can
pass
at each checkpoint to handle any arising issues.

>> Greetings,
>>
>> I'm going to be writing a one page "What You Need to Know" brochure
>> for our internal developers and application owners that bind to our AD
>> to provide security and other meta for their applications. We will be
>> going direct from 2000 to 2008 (we will do the forestprep in two steps
>> 20K to R2, R2 to 08) and we will be conduct a hardware replacement
>> which will complete the upgrade's DC swapout.
>>
>> I have the following bullet points so far:
>>
>> ----------------------------------------------------------------------
>> --------------------------------------------------------------
>>
>> - Schema Extension -
>>
>> This will only add attributes to the AD database schema, it will not
>> deactivate any attributes you are currently using. However, your
>> application performance may decrease while the Schema Extensions are
>> replicating. This will be done after-hours.
>>
>> - Hardware Replacement -
>>
>> We will conduct a one-for-one domain controller demotion/promotion and
>> will preserve the existing IP address. This will relieve the network
>> administrators from having to update the DHCP scopes and DNS zone
>> sharing settings. the NAMES, however, will change, thus if you are
>> binding to the directory using a fixed host name, we advise you to
>> take this op****tunity to follow best practices and update your code to
>> reference the domain name directly. The downtime period for each
>> replace domain controller will be one day, and will be performed
>> after-hours.
>>
>> - Domain Controller Security policies
>>
>> Base changes in the local security policy of the Windows Server 2008
>> operating system may have an effect on your bind to Active Directory.
>> The key changes that may affect you are .....
>>
>> - Global Catalog placement
>>
>> In the below chart please find the names of the servers which will
>> host the Global Catalog role. Please note some DC's replaced will no
>> longer hold the role. {add chart}
