You can select for the server to be automatically restarted or not after installation completes if it needs to restart.
Before you can replace your old computer with a new computer that is running a new version of Windows Server, you need to first prepare the Active Directory schema by running adprep.
The adprep console utility will upgrade the Active Directory schema to add new object types required by the new operating system.
Windows Server 2008 R2 (or earlier): You need to run adprep on the domain controller that owns the Schema Master FSMO role.
This is typically the root DC for the entire AD forest.
