A practical tour of GeoServer 3 covering upgrade steps, new requirements, refreshed UI, and updated module structure.
Learn what’s changed, what remains familiar, and how to transition from GeoServer 2.x efficiently, with a focus on real-world adoption and getting up to speed quickly.
GeoServer 3 introduces a modernized foundation while maintaining the familiar concepts and workflows that users rely on. This session offers a guided tour of the new release, focusing on what has changed in practice and how to approach the transition from GeoServer 2.x.
We’ll walk through the upgrade process, highlighting prerequisites such as updated Java and servlet container requirements, and what to expect when migrating existing installations. The session will also showcase the refreshed user interface, discussing its evolution and the improvements it brings in terms of usability and productivity.
In addition, we’ll explore the updated module structure, what is included in the core distribution, and how extensions are organized in GeoServer 3. Rather than covering every detail, the goal is to provide an overview of the new system and help users quickly get up to speed.
Join us for a practical overview of GeoServer 3, designed to make adoption straightforward and predictable for both new and existing users.
