Abstract

This document compares X.400(88) to X.400(84) and describes what problems can be anticipated in the migration, especially considering the migration from the existing X.400(84) infrastructure created by the COSINE MHS project to an X.400(88) infrastructure. It not only describes the technical complications, but also the effect the transition will have on the end users, especially concerning interworking between end users of the 84 and the 88 services.
