SBS 2008 Rebuild

Hi,

I have to re-build a SBS 2008 server. The only thing that I am unsure of is how to re-build it so that I preserve the current AD so that I don't have to re-configure all the users and computers.

I am building the new server in a VMWare ESXi Enviroment so I have the ability to run the new and old server simulateously.

I am just wanting someone to tell me the best method for migrating the AD. Exchange isn't an issue as email was moved to the cloud a while ago.

Thanks

Mark

You have to do an upgrae install.
Create an answer file and make sure it is available to the new installation program (eg a virtual floppy disk). AD will be copied across automatically.

Do check you AD and DNS are all correct before you start (run the best practices wizard on the old server and try and get it to give you a clean bill of health).

Read up on the upgrade docs - what you need to do is essentially the same as installing SBS2008 into a SBS2003 network, except that both source and target are 2008.

You will still have the restrictions on how long both servers can be running in parallel, and you should remove the old server from the network gracefully - otherwise you can get some references to it left in AD which can cause problems down the line.

You will be performing a migration. Microsoft has a SBS 2008 to SBS 2008 migration guide on TechNet. There are also several independent guides out there. When you install SBS 2008 in migration mode, it will migrate AD properly. You can skip the steps you don't need (mail, sharepoint, etc).

With that said, if you aren't using Exchange, you may want to consider taking this opportunity to move to a newer OS. SBS *really* doesn't play well without Exchange. Many of the wizards expect it, and it is memory heavy on top of that...eating a lot of valuable resources. Even disabling exchange services has negative impacts on the rest of SBS. As long as you are migrating anyways, now might be a worthwhile time to consider moving to 2012 Essentials or 2012 Standard, depending on the number of users you have.

Thanks for that. Do you have any of the links to the guides? I think I might build a couple VM's to practise with first.

I want to move away from SBS, however I can't get the spend authorised on the licenses. Also there may be a shift back to exchange in the next 12 months... Go figure!

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Can I run everything on the old SBS box after I have configured the new one? I don't want to have to cut everything over at once if I can avoid it. I want to be able to make sure the new server is correctly configured etc... As there are applications that need to be installed.

There is a very small window where both servers can coexist. It is not indefinite though so you must plan on decommissioning the old server. This is answered in the guide.
