Migrating from X.400(84) to X.400(88)
Status of this Memo
This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
Scope
In the context of a European pilot for an X.400(88) messaging
service, this document compares such a service to its X.400(84)
predecessor. It is aimed at a technical audience with a knowledge of
electronic mail in general and X.400 protocols in particular.
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.
