Hi,
I am currently running on Windows Server 2000 and this week I am getting new Server with Server 2003 OS and I am going to upgrading my old server with new one and I don't want to loose data. How can I do it!

Thanks,

i am going to assume that you are using Active Directory

can be done quite easily with a clean install of the new server

**Note - If introducing a 2003 R2 Server into the network as a DC you will need to run the ADPREP tools from the second cd

\CMPNENTS\R2\ADPREP

you can also download here
http://www.microsoft.com/downloads/details.aspx?familyid=5B73CF03-84DD-480F-98F9-526EC09E9BA8&displaylang=en

this boosts the schema up to cope with R2 functionality
http://www.microsoft.com/windowsserver2003/r2/whatsnewinr2.mspx

1) Promote your new machine as an additional domain controller in an already existing domain - this will allow AD to replicate to the new server
2) Make sure DNS is AD integrated on your old DC to allow all DNS replications also
3) Transfer the FSMO roles to the new server
http://www.petri.co.il/transferring_fsmo_roles.htm
http://support.microsoft.com/default.aspx?scid=kb;en-us;255690
4) Make the new DC a Global Catalog under Sites and Services
http://support.microsoft.com/?kbid=313994
5) Deactivate DHCP on the old DC (if used) and recreate the scope on the new DC, note if you have a fairly complex or Large DHCP scheme you may want to export and import the database
http://support.microsoft.com/kb/325473/
6) Run DCDIAG to make sure all is well and replication is fine
7) Demote the old DC if you dont intend to keep it as a backup
8) Recreate Shares etc on the new server
9) Reinstall printers and share them etc....


this will allow you to have the complete AD directory on the new DC and clients will barely be aware of any changes

you need to run all your prep tools on the current 2000 machines

once you promote your new 2003 machine in, then you can transfer the FSMO roles on either machine

let me know if you need more

I just found that whoever make the OLD DC they make it as the real DNS that starts with other domains real IP address, so I am unable to create child domain in the main domain as I don't have the access to create child domain in the present DC. So I need to create new DC on the NEW SERVER and than assign DNS of that computer 127..0.0.1. I already did that and now I want to copy the user profiles from the OLD DC and want to paste in the NEW DC, is there any way I can move user profile to the newDC so user's data remains the same and they don't feel any headache. One more thing I would like to make a logon script that remains the same for specific user so user can logon to any computer and they found the same settings of the desktop and email client.

Thanks jay jay70

you can use the user state migration tool for the actual profiles
http://support.microsoft.com/kb/321197/en-us

and the ADMT tool to migrate the actual accounts

look at roaming profiles for your users
