The purpose of this thesis is to present and describe which criteria, according to the system family Configuration Management, should be met when developing a CM-tool to handle migration data. ACT is a tool developed by Microsoft to gather information about, analyze, test and mitigate applications in a network when migrating the IT-infrastructure of an organization to a new operating system. The organization that is being studied wants to present the data about the analyzed applications in such a way, that a customer can choose what to mitigate and migrate. The goal is therefore to develop a prototype (CM-tool) that will present this data. The study has shown that ACT lacks certain requirements stated by the organization when it comes to presentation. But when it comes to the rest of the functions, ACT performs as expected. The investigation resulted in specifications and technical solution for the new CM-tool. CMcriteria for migration data was put forth and parts of the prototype were also developed.
