Planning an active directory (DNS) migration 2000 -> 2003 R2

Hi,

Currently we have a windows 2000 Domain Controller (Server A) in the Netherlands that we are planning to migrate to a big new windows 2003 R2 server.(Server C). Becuase our old domain controller (A) is short in HD space we have used an available w2k fileserver (Server B) to solve our storage problems for now.
After the domain migration we want to consolidate the storage on A and B on C.

Theres one catch: we want to preserve all fileowners/rights and we want to migrate the a new ad/dns structure..

The company i work for has a branch office in china, where no AD is being used yet! After the domain migration in the netherlands is ready/done, we want to interconnect the chinese site in the AD using our VPN site-to-site connection. There is a new server waiting in china to be used. Since we think our windows 2000 active directory domain is dirty in Holland and we have the ability to start clean now, we are wondering what steps to take...

Our company uses the domain hm.nl internally and hollandmechanics.com for email externally.
hm.nl is of no meaning to us and has been made up by a hired systemadministrator in the past who didnt know we would expand our AD site eventually :-)

we would like to use hollandmechanics.com as our domain and china to be china.hollandmechanics.com and not china.hm.nl because the name makes no sense.
*1) Is this stupid to think?

Because i'm no cerfitied microsoft engineer but just a  c++ developer, domain migrations are new to me.. I'm not stupid and i can read and execute well, but lets face it... this isnt my job :-)

Since we wont preform all the migration taks by ourselfs and are hiring a company for that...
we want to prepare us as much as possible and do as much as stupid tasks as possible like expanding/combing two file servers with their data...

i want to know what i can do and what would be the best way...

*2) Can i add the new fileserver (Server C) to the current hm.nl domain (as a domain member) so i can transfer all files and user/rights and combine that with the files from the 2nd file server (B)?

*3) Is it better to transfer all files from A to B, combine them there... wait for the domain/user migration to be ready and then transfer all the files to new server (C).

*4) is it wise to change the DNS naming? its look prettier using .com and for future expension it also makes more sence..

*5) Can china start using/deploying an AD site under the name china.hollandmechanics.com ? so we can interconnect the sites later or does that have to wait..

*6) can an hm.nl AD domain excists next to a hollandmechanics.com AD domain on the same network?


What to do? I hope someone can help me.

Best regards,

A couple of points....

I don't think it wise to migrate AND change the domain name at the same time.  It can be done but it sure would make things more complicated.
So, either change the internal domain name first or migrate to the new server and 2003 AD first.  Generally Interanl domain names are of the form hollandmechanics.local  It is usually not a good idea to make the internal domain name the same as the public domain name.  Again, It can be done buy it makes thing more complicated.

I would go ahead and setup the new server as a member server and consolidate your files on there.  No need to go from A to B then C.

If you want china to be a sepeate domain, then they can go ahead and start now.  Otherwise if they are to be a seperate site within a single domain, then you need to get that domain/forest in it's final form before adding china to it.  Again - it's more complicated to be migrating and adding at the same time.

Hope this helps some.

hi,

Internally we have agreed to first promote the new server 2003 server as a DC and then demote the old server..
Copy all the files and make the AD 2003 native (no mixed env.)

after that we I still want to change the domain name and dns namespace..
i read that this can only be done in a windows 2003 domain and also discovered that hollandmechanics(.com) is too long for a valid dns host name (15 characters max)

so now i want to make it hm.local

One thing I am still wondering, can I also name our domain controller nl.hm.local?
i want china to be in the same namespace -> cn.hm.local

is this valid and can it be done in a AD design?

Best regards,
Rick

to make another comment on this :-)

After we have migrated to a new W2003 DC, the old 2000 DC will be demoted...
In china we have a 2003 DC waiting to be deployed...
So eventually there will be only two DC's in the forest


What would be the best (dns) namingscheme?
I think it is nicest if all computers in the netherlands have a wrkstn.nl.hm.local dns name (again if possible)
in stead of
wrkstn.hm.local
