Successful Operation on the Open Heart (German talk at Java conference Jax)

At the Jax conference which took place in Mainz from April 20 through April 24, 2015, GameDuell’s Software Architect Dirk Ehms spoke about practical solutions for the migration from JEE 6 to JEE 7 that we performed on our modular online platform with over 100 servers. To achieve this, we migrated our entire platform infrastructure with 300 Maven modules from Glassfish 3.2 to 4.0.1. Dirk explained how our team had to overcome challenges in the backwards compatibility of both server versions and described the concrete steps that allowed us to maintain our continuous build and release process without any downtime throughout the switch to the new version. His full presentation is available below via SlideShare.
