Abstract

How do you migrate an enterprise application which has decades old legacy code running on an IBM Z-series mainframe? What options do you have and how do you estimate the efforts best? In this paper, we present a model developed during a real-world case study of a migration endeavour of the worldwide warranty system at a major premium automotive. We present a pragmatic approach taken to ballpark migration efforts which allows for similar endeavours to estimate migration efforts in a similar fashion.
