Towards Identification of Migration Increments to Enable Smooth Migration

Abstract

The migration of existing systems is a major problem in today's enterprises. These systems, which are often called legacy systems, are usually business critical, but difficult to adapt to new business requirements. A promising solution is the smooth migration of these systems, i.e. the systems are integrated into the system landscape and then migrated in a number of smaller steps. This leads to the question of how these steps can be identified. We propose a method based on a dependency model of the existing system and graph clustering analyses to identify these steps and define migration increments.
