Replacing SBS2003

I plan on replacing an SBS2003 server with a Windows Server 2008 Enterprise server.  Currently the SBS2003 is the domain controller/DHCP Server/Active Directory.  There is currently a Windows Server 2003 standard within the network being used as a Terminal Server.

What are the recommended procedures in moving the domain controller/DHCP Server/Active Directory services/information from the SBS2003 server to the new 2008 Server?

Why 2008?  It was replaced by 2008 R2 and very soon by Server 2012, which has better pricing than 2008 R2.  Just curios.

Glen Knight has good documentation on your migration scenario:
Migrate Small Business Server 2003 to Exchange 2010 and Windows 2008 R2
http://demazter.wordpress.com/2010/04/29/migrate-small-business-server-2003-to-exchange-2010-and-windows-2008-r2/

My preference is a migration kit from www.swingmigration.com who specialize in SBS migrations, including your scenario.  They provide documentation, a means to revet back to your original server, tools, and 90 days support for the migration.

RobWill, it is 2008R2.  Exchange isn't being used on the SBS as we use a Hosted Microsoft Exchange Service.

Since there already is a 2003 Server standard in the network, can we promote that server to host the domain controller/DHCP Server/Active Directory services, replace the SBS 2003 server then promote the new 2008R2 server?

Once this project is done, the 2003 standard Terminal Server is being replaced as well.

Do the following...
- You will need to prep the Forest and Domain to allow a 2008 server to be a DC
- Run adprep /forestprep (on the Schema Master)
- Run adprep /domainprep /gpprep (on the Infrastructure Master)
- Load Windows 2008 on a VM or Physical server
- Join 2008 Server to the domain
- On the 2008 server run dcpromo /adv (I use /adv to view all options)
- Promote your 2008 server as a DC (Make sure that you have it as a GC as well)
- Install the DNS Role
- Check/wait for AD Replication
- Transfer all FSMO Roles from sbs2003 to server 2008
- Install DHCP Role, migrate settings - http://support.microsoft.com/kb/962355
- Demote sbs2003 server as a domain controller
- Ensure that Sites and Services have removed the DC, if not manually remove
- Check DNS to ensure that sbs2003 server is no longer a Name Server
- Also _MSDCS Folder to ensure there are no remnates of sbs2003 server (remove if they still exists)

Hope this helps

I appreciate the info.  I plan on implementing next weekend.  I will keep you all posted.

You have o be very careful when migrating SBS, it is not server standard, however that may not come into play as much where you are not using Exchange, but there is Exchange info within AD which will be migrated and users will still point to it. Exchange needs to be properly removed as in the documentation, and there is more.

As for using the existing serer 2003, you can migrate to it but it is a VERY discouraged practice to run terminal services on a DC, and there are customizations required to do so.  Terminal Servers are optimized for 'foreground' applications, not background services like AD and file & print.  The permissions on a TS are different, and there are security concerns with allowing users access to a DC.  If doing so I would back up your TS CAL's remove terminal services, migrate and restore terminal services, but again it is a bad practice.

Server 2008 R2 will allow more RAM and flexibility (including multi-monitor support in TS sessions) , plus with your Enterprise license you have 4 server licenses to use.  Keep in mind if you remove the SBS you need to buy all new CAL's rather than waste that money on 2003 stanadard CAL's I would buy 2008 R2 CAL's which will also allow access to the 2003 server if in the same domain.

We purchased CAL's forthe 2008R2, so we are good there.  Ok, i will not touch the terminal server.

Ulimately, we plan on migrating the two physical servers (1 SBS2003 and 1 Server 2003 Std Terminal Server) to VM's.

We have purchased the new server and plan on installing 3 virtual machines.  (1 Server 2008R2 to replace the SBS2003, one Server 2008R2 to replace the 2003 TS and one test server).  This is the reason we went with the Enterprise version.

How about if we configure the new "test server" VM to host the domain controller/DHCP Server/Active Directory, implement the SBS replacement server, then move all the services back?

I had asked about why 2008 originally as i assumed you were buying new.  2008 R2 is great, especially if you already have licensing.

>>"Ulimately, we plan on migrating the two physical servers (1 SBS2003 and 1 Server 2003 Std Terminal Server) to VM's."
Good plan.

Based on your plans, Enterprise was a good investment.

Not sure I understand your last point; move SBS to temp DC then back to SBS?  If so SBS is a pain to migrate, not something you want to do twice.  However the Swingmigration.com option I mentioned earlier does that with any migration.  They use a temporary DC to move from hold hardware/VM to new hardware/VM.  The reason being is you can do it in stages and revert back at any point as you do not 'destroy' the original O/S.  They have scenarios for going SBS to anything; same version, different version, non-SBS, on same hardware or different hardware.

ok, I will take a look at swingmigration.com.  is is free or paid software?

The reason I stated moving to a temp server was to not touch the current TS.  I thought we could configure the TS to host the domain controller/DHCP Server/Active Directory but from the comments above, it would be too messy and not recommended.

So thought it would be easier to configure a temp server to migrate the domain controller/DHCP Server/Active Directory, replace the SBS 2003 server with the new 2008R2 server, then migrate the domain controller/DHCP Server/Active Directory to the new 2008R2 server.

Swingmigration is $395, for the record I have no ties.  It's a frequently suggested option here on EE.
I would virtualize the existing SBS, Then migrate to 2008 R2 when ready.

ptsolutionsincAuthor Commented:
Why would you virtualize the SBS server first?  In case something goes wrong with the migration we can revert back to the physical server?

Rob WilliamsCommented:
Sorry no need to do so but I assumed you were wanting to move to all VM's right away.  That is why I thought you were going to use a temp server.

ptsolutionsincAuthor Commented:
No the temp server was just going to be used for future testing.

I was going by your comment; "So thought it would be easier to configure a temp server to migrate the domain controller/DHCP Server/Active Directory, replace the SBS 2003 server with the new 2008R2 server, then migrate the domain controller/DHCP Server/Active Directory to the new 2008R2 server. "
Not sure I follow......but I am a little slow sometimes  :-)

Robwill, we invested in the Swingmigration kit and it worked like a charm.  Thanks for the recommendation.
