Migration from JEE-6 to JEE-7 in full live operations

JAXenter published a detailed report of our Software Architect Dirk Ehms in which he explains the migration of our games and community platform based on over 300 Maven modules from JEE-6 to JEE-7.

The approach that our team applied allowed us to maintain the continuous build and release process with 70 developers constantly working on the code basis of over 100 Glassfish application servers. The practical solutions of this uncomplicated approach that is described in this article could also be adapted to other migration projects. Read Dirk’s article that is based on a talk he gave at the JAX 2015 conference on JAXenter (in German). The presentation slides of his talk are still available in this recent post.
