We have small Network:
1) 20 PC’s running Windows 2000 and XP.
2) One PDC Server runs Windows NT.4 Server (there is no BDC Server).
3) One member Server runs Windows NT.4 Server and Exchange Server 5.5.
Now we joined with other small company:
1) 10 PC’s running Windows 2000 and XP.
2) One PDC Server runs Windows 2003 server.
3) One member Server runs Windows 2003 server and Exchange Server 2003.
We need to replace the new company servers with all of its Current PDC Windows 2003 Server and Exchange 2003 configurations, and joint them to our Current NT.4 Network.
1) Replace the new company servers with all of its PDC Windows 2003 Server and Exchange 2003 configurations, and joint them to our Current NT.4 Network.
2) Use the new exchange 2003 Server without changing its current configuration (change only the Exchange 2003 name to joint the NT.4 Domain)
3) Use the new Domain 2003 Server without changing its current configuration (change only the Domain 2003 name to coexist with the NT.4 Domain)
4) Move all User Accounts and all Data from NT Domain to 2003 Domain.
5) Move all Exchange 5.5 User Accounts, Mail Box’s, and Public Folder ….etc to the Exchange 2003.
6) Remove the old NT.4 Domain and Exchange 5.5 from the Network.
Please I am in need of anyone help to let me know how I can do this complicated job.
