PartDesign Migrate

Description
Files created with older freecad versions can still be opened and edited. If pure part design feature based they can be converted to the new style via the menu ->PartDesign -> Migrate. If they are mixed Part / Part Design/ Draft the conversion will most likely fail.

Note that 0.17 development version has seen and will see many changes, it is not recommended to do any real work with it in the next time as it is unstable. 0.16 files can be opened and the features can be edited, but it is not possible to create new features. This works only in the new workflow with bodies. If it is a PartDesign only model you can try menu->PartDesign->Migrate ickby in this topic
