Workflow doesn't work after a SharePoint upgrade from 2007 to 2010

If you upgrade WSS 3.0 to SharePoint Foundation 2010, your workflow may work fine until you touch it. After you re-publish it, you may find that it doesn't operate any longer. Check the general properties of the workflow. You may find that the workflow is not attached to any operation (Manual, On Insert, or On Change). It looks like the upgrade doesn't carry over this property and once recompiled (re-published) it is disconnected from it source list (at least in our case).

It may apply to SharePoint Server version but I didn't check this.
