Abstract

Performing a migration of a legacy system can often be a daunting task. However, there often comes a time where maintaining a legacy system is not profitable. At such a time, estimating how much effort is required to preform a migration can be vital for the legacy system holders. This project was formed to help the estimation process by documenting how effort is distributed over different activities during a migration. A framework was created since there is no formal, generally accepted method for system migrations. This thesis takes an abductive approach, combining an inductive approach used in the creation of a framework and a deductive approach to document how effort was distributed during the migration. A framework was created using the literature study and this framework was used to conduct a case study.

The result of this case study was an updated framework and a table presenting the effort distribution of the migration. The framework showed factors that were influential when migrating the system. The effort distribution presents how effort is distributed over activities and shows which activities during the migration required more effort. 

Finally the thesis concludes that effort is highly centered around the realization phase of the migration. Understanding legacy systems can be a challenge, lacking documentation and issues brought by the lack of maintenance results in high effort during this phase. Allocating more resources for the realization phase and having access to people with experience during the preparation phase would likely make for a smoother transition with less unidentified problems appearing.
