So we're once again in our series of how to prepare for a migration.

To recap, we read, we watched. 

We ran the www.sbsbpa.com on the server

We ran the IT Environmental Health scanner - http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=dd7a00df-1a5b-4fb6-a8a6-657a7968bd11 to ensure all was well.

We checked the primary account.

We took a backup.

We took a system state backup.

{heck we even used the Disk2vhd to move it to a test bed just so we can run this test before doing this for real}

We're now ready for the Migration prep tool:

H.  On the Source Server, run the SBS 2008 migration prep tool.

This tool performs the following actions:

1. Installs update 943494 on the SBS 2003 server to extend the migration grace period from 7 to 21 days.
2. Runs ADPREP to update the forest, domain, and group policy object access control entries.
3. Changes Exchange 2003 from Mixed mode to Native mode.
4. Adds the Authenticated Users group to the Pre-Windows 2000 security group.

If Exchange 2003 is not running in Native mode, Exchange Server 2007 will not be installed and you will have to start all over. The error message is Exchange Server 2007 cannot be installed. For more information, see this.

If the Authenticated Users group is not a member of the Pre-Windows 2000 security group, then standard users will not be able to access the Remote Web Workplace. The error message they will see is: Cannot connect to the Remote Web Workplace site. To continue, contact your network administrator.

The tool can be found on the SBS 2008 media under the tools folder.  If you don't have a DVD on the SBS 2003 (like I don't) stick the DVD in any other computer, copy the tools folder onto removable media and put it on the SBS 2003.

Now that we have umpteen backups, on the SBS 2003 box launch that Sourcetool.exe file

We have a backup so we're going to check the box.

The installer starts

When it finishes it's now prepared the SBS 2003 for the migration.

What it did in the background is install

Application KB943494 (Hotfix for Windows Server 2003 (KB943494)) was installed.
Does the ADprep and flips Exchange to native mode
Adds the Authenticated Users group to the Pre-Windows 2000 security group

  MESSAGE Security Enabled Local Group Changed:
Target Account Name: Pre-Windows 2000 Compatible Access
Target Domain: Builtin
Target Account ID: BUILTIN\Pre-Windows 2000 Compatible Access

Reboot and we're ready for the next step.

Next step building the answer file.
