Calculating migration points for application migration

摘要

Embodiments of the present invention relate to “migration points” and an associated method and calculation tool. In general, a migration point is a number that represents an evaluation of the size and complexity of performing a migration, port, or refresh of an application from a legacy platform to a new target platform. When migration points are applied to applications across a portfolio, the migration points provide a relative measurement of the size and complexity necessary to perform the migration. Additionally, this measurement can be used to make a determination in calculating migration productivity (i.e., migration points divided by person-months, similar to how software productivity utilizes function points). In a typical embodiment, the migration point total is based on a set of qualitative migration points and a set of quantitative migration points, which are based on various technical aspects of the application, operating system, and hardware involved with the migration process.
