Issues while upgrading from Windows 2003 to Windows 2008

Recently, we were trying to upgrade WIndows 2003 to WIndows 2008. WHile trying to upgrade, we ran into couple of intresting issues. This blogs talks about the issue faces during the upgrade.

 

First issue:

 

So the first thing which we would need is to update the version on Windows 2003 to Windows 2003 SP1. So, we will upgrade to windows 2003 SP2, reboot and again try to upgrade to Windows 2008.

 Second Issue:

Hence we would need to run the Adprep command ( Adprep from Windows 2008). So, we will run the command adprep /forestprep

Type C in the command prompt and hit enter. Once it completes, then we need to run

Adprep /domainprep

D:\sources\adprep>adprep /domainprep

Running domainprep ...  

Adprep detected that the domain is not in native mode

[Status/Consequence]

Adprep has stopped without making changes.

[User Action]

Configure the domain to run in native mode and re-run domainprep

Third Issue:

"Configure the domain to run in native mode and re-run domainprep"

Hence we make the changes below:

And then again run the command and this time it is successful:

 

ADPREP /forestprep must be run on the Schema Master of a forest and under the credentials of someone in the Schema Admins and Enterprise Admins groups.

ADPREP /domainprep must be run on the Infrastructure Master of a domain and under the credentials of someone in the Domain Admins group.

 

Once the above issues were fixed, we were able to install and add a WIndows 2008 into the domain.
