Microsoft: Upgrade Windows Server 2008 to R2

Today I started with upgrading my production Windows 2008 PDC’s to the R2 release. After mounting the Windows 2008 R2 DVD I received two warnings:

– You must have 15 GB of free space (it’s VMware.. so what’s the problem?)

– Prepare a Windows Server 2003 Forest Schema for a Domain Controller that runs Windows Server 2008 or Windows Server 2008 R2

To do step 2 you need to do a few things:

– Mount Windows Server 2008 R2 cd-rom

– Start CMD with Administrator rights (run as Administrator)

– Type: D:\Support\adprep\adprep /forestprep [Enter]

VMpros 2010

– Type: C [Enter]

– Type: adprep /domainprep [Enter]

You can now upgrade your Windows to Windows Server 2008 R2
