The Migration Problem of GKS-3D and PHIGS is discussed in this report under the view of the graphics reference model's description technique: the component and framework concept. Therefore the components of GKS-3D and PHIGS are defined. The common and different concepts are indicated and the mapping from PHIGS to GKS-3D and from GKS-3D to PHIGS is done. This mapping is performed only on the components which have been proved as a description technique suited for such purposes. The migration has two different aspects. One is the theoretical approach to prove that such a migration is possible. The other one is more practical. It gives guide-lines for the use of PHIGS and GKS-3D and shows under which circumstances both can be used together.
