1. Now is the time to prep the domain for the 2008 Server which if you was migrating from a SBS 2003 Server you would put the SBS 2008 DVD in and run the Migration Prep Tool and do these steps. Well this is not a SBS 2003 Server so you would open a command prompt browse to the DVD Drive and the Tools Folder and the ADPrep Folder. Then run adprep /forestprep and then once that completes give it a while and then run adprep /domainprep and then once that finishes you can just to be sure run adprep /domainprep /gpprep usually this will return you don’t need to run this.
2. Once that is all done it is time to run the Answer File Tool to create a answer file for the migration. You will be using a little USB Flash drive and what you do is plug this into your Source Server and then Browsing to Tools folder on the DVD and running the SBSAfg file. Usually I will select the attended install meaning uncheck the box that says run unattended just so I can verify the information as the migration starts. I also select to Migrate from existing server (join existing domain) and to download Updates. You can select unattended but you need to be darn sure you have all your information correct. One thing to be aware of is where it asks for the Certificate Authority Name do not put the name of your email domain i.e. mail.whatever.com. Leaving it blank is acceptable or Company Name CA or whatever you feel like just not your domain name so leaving this blank is good. So once you are sure everything is the way you want it save your Answer File to the USB Flash drive.
3. Now is the time to start the install of the SBS 2008 by booting your new server to the DVD and you do not have to have your USB Drive plugged into the destination server at this point. Some servers will try and boot to the USB drive if you have it plugged in so it is best to leave it out until it is time for it to be plugged in. which is after the second server reboot if I remember correctly. If you miss this and the server goes to the new install without reading your USB Drive. Hit cancel reboot the server with the USB Drive in and away you go. That is why I select to do a attended install so I can watch what is happening plus to verify the customer info. You can configure you hard drive partitions before or during the SBS 2008. On the HP servers we have the option to configure the Partition sizes during the boot process and it will depend on what you are using for a server and RAID Controller if you can do this before or not. MS recommends a 60 Gig C Drive size I say 100 Gig.
4. Also be sure in the BIOS of your server you have the time and date set correctly before installing.
You then would follow along with the Documentation from Microsoft on a SBS 2003 to SBS 2008 migration paper, the steps for walking though the whole migration is on this. Basically what it boils down to is you can use the SBS 2003 to SBS 2008 migration doc you just cannot use the Source Tool to Adprep your domain on the 2003 Server and you use the install DVD to Prep your forest and domain. I would really suggest if you have not been testing this that you do 10 to 20 migrations in your test lab to get yourself ready for this as it is a whole new way of migrating. Also if you do not want to remove the old server it can run as a DC in the domain after the SBS 2008 server is on the domain and has all the Roles moved to it. This is only true with a Standard 2003 Server and not SBS2003
