I have 2 Domain controllers connect together with external 1 way connection and they both use windows server 2003. Both domains are on a different forest. I need to demode one of them but i have been instructed to change the functionality on one of them to windows server 2008. Is that possible, will it cause any problems ? How am i going to do that ?

Hi

Change the functional level to server 2008 or upgrade the OS from 2003 to 2008? If the latter, it is quit simple, watch this step by step.

Personally i would demote the second DC in advance and make a full backup of the remaining before proceeding the upgrade.

Hello Patrick,

Thank you so much for your video, i already bookmark it. But i want to change the functional level to server 2008, i do not want to upgrade to 2008 ! Been told that i have to pay a lot of attention there to the DNS, but i did not do anything yet to be honest. Any advise?

Thanks

Hi again,

Ok, so if you have 2 2003 DC's i see no harm in upgrading the functional level to 2008. ( i do not advise to go to 2008 r2 in one step )
This is done is Active Directory Domains and Trusts-> Right click AD Domains and trust and select 'Raise functional level'
Always make sure you take a bare metal backup in case you need to go back.

Just to be curious, what functionallity do you need what justifies this functional level upgrade?

Hello Patrick,
Thank you so much my friend. Yes indeed there is no harm for the functional level to 2008. I have raise the functional level successfully !:) Yes backup is always in my mind for everything i do.
Well i don't know what justifies this functional level upgrade to be honest but i am pretty sure some software application the software engineers wanted to install and they wanted that functional level to be 2008. They ask, i have to deliver ! Again Patrick , thank you so much my friend , much appreciated !
