Running TFS 2008 build definitions with TFS 2010

Question

I am in the process of upgrading my builds from TFS 2008 to TFS 2010, and in the meanwhile, I am using the Upgrade template to use the TFS 2008 build definitions. I have installed both a build controller and build agent on the machine that used to run previous builds while I was on TFS 2008. The said machine still has TFS 2008 build service installed.

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\TeamBuild\Microsoft.TeamFoundation.Build.targets" />
<Import Project="$(MSBuildExtensionsPath32)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets" />
<Import Project="$(MSBuildExtensionsPath32)\ExtensionPack\MSBuild.ExtensionPack.tasks"/>

It seems like the first Import target causes the following error, but I can't figure out how to resolve it (the file path is from the machine running the upgrade template on TFS 2010.

C:\Program Files\MSBuild\Microsoft\VisualStudio\TeamBuild\Microsoft.TeamFoundation
.Build.targets (278): The "Microsoft.TeamFoundation.Build.Tasks.GetBuildProperties"
task could not be loaded from the assembly C:\Program Files\Microsoft Team Foundation 
Server 2010\Tools\\Microsoft.TeamFoundation.Build.Tasks.dll. Could not load file or 
assembly 'file:///C:\Program Files\Microsoft Team Foundation Server 2010\Tools\
Microsoft.TeamFoundation.Build.Tasks.dll' or one of its dependencies. The system cannot 
find the file specified. Confirm that the <UsingTask> declaration is correct, that the 
assembly and all its dependencies are available, and that the task contains a public 
class that implements Microsoft.Build.Framework.ITask.'

I have tried the solution offered in here, but to no avail.

Any help would be greatly appreciated.

You need to ensure the the imports are pointing to the 2008 Microsoft.TeamFoundation.Build.Tasks.dll

so $(MSBuildExtensionsPath32) == what?

Looing at the error message : its

C:\Program Files\Microsoft Team Foundation 
Server 2010\Tools\

Run the build with /verbosity:diagnostic to see what the variables are then, correct them in the team build rsp file.
