Domain Migration from NT4 to Win2003

Hi there.

We have SAP R/3 ENTERPRISE 47X110, kernel 6.20 on ORACLE

database.The SAP Application and the Oracle Database are installed on

Win2000 servers.

Please note that the SAP and Oracle Servers are running on Win2000, but

they are members of a windows NT4 Domain.

Now, we have decided to Upgrade our environment from NT4 domain to a

Win2003 domain.

Can you please advise us, about possible problems with the SAP and Oracle

Servers related with the Domain Upgrade (for example problems with domain user <SYS>adm)?

    The migration from an NT 4.0 domain and an Active Directory Domain is no real migration but a new setup since the structure of AD is different than the NT 4.0 domain.

    The clean way would be to backup your SAP system, install the Windows 2000 server (or better 2003 since W2K is already out of maintenance) in the domain and reinstall the system using the backup. This will ensure all necessary permissions are correctly set.

    If you add the W2K machine to the domain without a reinstallation, you need to make sure (manually), that all permissions are set appropriately, passwords are synchronized and the database is aware of the changes.
