The technology used in the development of web-applications is evolving at such rate that it has become more and more important to keep web-applications modern. If an application is based on a technical platform that is not renewed, the platform may over time develop into an obstacle in further development of the application. There may be compatibility issues and some of the code may be unnecessary due to abstraction, and therefore more time consuming to work with. Sometimes the reason may be that an application has been built to run, and is running on an application server that is no longer being maintained. The system can be large and modernization can cost a lot. In the study conducted and written about in the report, the task is to look at what possibilities there are to cost-effectively perform such a modernization. In the study two general modernization methods are identified, which define two different approaches that are studied. The different modernization approaches are tested in modernization of a web-based Java application to see advantages and disadvantages. The study results in two solutions, one more costly but that can have some benefits and another more cost-effective but that can be more short-sighted.
