Organizations periodically update their desktop operating system (OS) for various critical reasons. To ensure business continuity, any software application incompatibility threat should be anticipated. Therefore all applications need to be tested and re-deployed to the new desktop OS. In large organizations application portfolio migration projects could span for far more than one year. However the reality is that organizations use many different COTS applications, which adhere to different standards and require different techniques to function properly within an organization. This makes predicting the required time and budget even in the best cases a mere informed guess.

The uncertainty on the time needed to migrate a software application introduces many difficulties in project planning and it clouds the possibilities for project optimization. Moreover it could make managers uncertain, hence delay or even cancel critical updates, resulting in a loss of business opportunities.

In our study we analyzed application portfolio migrations, we identified and ranked more than a dozen key factors that contribute to the complexity of application portfolio migrations and investigated their impact at a large Dutch insurance company. Based on these insights we devised an instrument to configure application portfolio migration projects for efficiency. Our method provides a generative basis that can be easily extended with new strategies for factors that were uncovered so far.
