Abstract
An enterprise has a challenge in keeping pace with the quickly evolving technology. The biggest challenge comes in terms of legacy application migration to technologies like cloud. Legacy application migration should be well thought out at the very start (i.e., pre-migration and supported by migration framework). In this chapter, the author proposes a legacy application migration framework with a focus on pre-migration area. A robust technical and business analysis of existing/legacy applications, based on the enterprise's focus parameters, during pre-migration sets the migration path for subsequent area of framework. The proposed pre-migration mathematical assessment helps an enterprise to understand a legacy application's current state and also helps in unearthing the information with respect to candidate application and helps in taking well-informed decisions like GO or NO-GO w.r.t legacy application migration. Considering application migration a journey, it is important that it reaches its destination, so pre-migration is an important area of the migration journey.
