In Support of an Aspect-oriented Approach to Migrating Distributed Applications

Migrating distributed applications from one middleware to another is difficult in legacy software systems where middleware functionality is spread across and tangled with business logic. In these systems, the old middleware code has to be removed before the application is refactored and the new middleware functionality is added. However, when distributed applications are developed in an aspect-oriented modeldriven development environment, the need to extract the old middleware before application migration proceeds may not exist. This paper motivates and illustrates the need for an aspect-oriented approach to distributed application migration in model driven development environments.
