I am trying to import TFS 2005 into TFS 2010 using tfsconfig import command. When running the command I receive error TF255217: The specific database (TfsIntegration) is not upgradable. After researching, I believe this is due to missing extended properties on the database. However, looking back at the original TFS 2005 database reveals it has no extended properties either. I believe the properties I need are:
TFS_INSTANCE
TFS_INT_PROTOCOL_VERSION
TFS_PRODUCT_VERSION
How can I find out what these properties should be set to?
