Migration by the numbers – Step 5

Step 5 in a series of posts documenting the Microsoft SharePoint Foundation 2010 upgrade process on SBS 2008. This is based on the document:

Step 5: Uninstall Windows SharePoint Services 3.0 and edit the Registry

Before you go any further I would suggest that you consider what your recovery plan is if everything goes pear shaped. One of the things that this process doesn’t help you with is recovering a SharePoint v3 installation on SBS 2008. If you don’t know how to do that then I suggest you make sure you at least understand what maybe required to recover SharePoint v3 on SBS 2008, given the steps you are about to take.

 

You need to firstly download the SharePoint Foundation 2010 installation file from http://go.microsoft.com/fwlink/?LinkId=191959. The size is about 170MB so make sure you get the complete copy.

 

Download the file to you SBS 2008 and run it. After expanding some file you should be greeted by the following splash screen.

Select the option Install software prerequisites under the Install section.

You will then be greeted with a complete list of software that needs to be installed on your server prior to SharePoint 2010 being installed.

 

Press the Next button to continue.

Accept the EULA and press the Next button to continue.

The first step will be the automatic configuration of the IIS server. This process may take a few minutes so be patient.

Once that is complete you should see the required software being downloaded and installed on your system.

You should also see a number of updates being downloaded and installed. This is going to most likely mean a reboot once this process is complete.

So you may want to keep an eye on the process and delay the pending reboot until the prerequisite process is complete.

When the process is complete you should see the displayed above. Beware, that in my experience if your machine needs a reboot and you press the Finish button your SBS 2008 will automatically recommence a reboot. So make sure you are aware of that.

 

Even if the server doesn’t need to reboot it, I would just to ensure everything comes up cleanly.

 

Most likely the SharePoint Foundation 2010 installation will re-launch and start configuring the Web Server again.

No fear, just let the process complete (it may take several minutes).

 

Once the server has rebooted this is where the real fun begins. Log back into your SBS 2008 server and select Control Panel and the Programs and Features.

Ok, deep breath. Select Microsoft Windows SharePoint Services 3.0 from the list of installed programs and then select Uninstall from the top.

 

Accept the UAC.

Press the Yes button.

Your last warning to make sure you REALLY want to do this! Press OK to continue.

Wave bye bye to Windows SharePoint Services v3 on your SBS 2008 server.

Your SBS 2008 server is now SharePoint free. Press Close.

 

Run regedit and accept the UAC presented. Navigate to the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\VssAccessControl\.

So the Microsoft documentation says:

 

4. Double-click NETWORK SERVICE, and then, in Value data, type 1.

 

In my situation above I have a NETWORK SERVICE and a NetworkService entry but the NETWORK SERVICE not set to 1. So I double clicked on the second entry and changed the value to 1 and selected OK.

Next step is to install SharePoint Foundation 2010 on SBS 2008.
