Recently saw a lot of posts from the win Server 2003 AD upgrade, many of them say there is no way to upgrade directly, but need to upgrade to win Server 2008 or R2 and then upgrade to win server 2012 R2. This explanation is incorrect, and there are some assertions that you can upgrade directly, but it is not true that you cannot deploy an RODC read-only domain control in a domain environment after an upgrade.

We can upgrade directly from the Server 2003 AD to server R2, during the deployment of the win server R2 secondary domain control through the Adprep.exe Preparation tool: "Forest and schema preparation" and "Domain preparation", Instead of preparing for the RODC read-only domain control, if we want to deploy the RODC read-only domain control later, we only need to execute the ADPREP.EXE/RODCPREP.

The following I will be from the win Server 2003 AD upgrade to win server R2 process to share to everyone, I hope to help you.

1. Win Server 2003 domain-controlled deployment (this process is a little)

2. Elevate the domain and forest functional level of the win Server 2003 ad from Win Server 2000 to win Server 2003

6. Deploying RODC read-only domain control

We report the following warning when we add an RODC read-only domain control account
