The software ezScrum is a legacy web application that has been developed and maintained for more than ten years. With web technology constantly evolving, the ezScrum development team has found it increasingly difficult to keep up and many older technologies are still used. A consequence is the slowdown of release. Examining the issues, we have found the main cause to be the coupling of ezScrum modules since ezScrum is a monolith. Thus, effort has been taken to convert ezScrum into a set of microservices so that coupling is reduced. This thesis reports our work on extracting the product backlog from ezScrum. As demonstrated, the extracted product backlog microservice operates as an independent web application that collaborates with other extracted microservices from ezScrum including account management.
