I have been migrating SharePoint 2007 to a SharePoint 2010 installation.
The upgrade completes successfully but the association between workflows and lists is lost.
In the SharePoint 2007 there are workflows "Approval" and "Collect Feedback" on all lists. After the upgrade the following message appears for all lists on SharePoint 2010: "There are no workflows currently available to start on this item"
The only way I can see to get these back is to go through each list indiviually and reapply workflows - I wish to avoid this as there's hundreds of lists.
All workflow features have been activated. It is the enterprise edition.
