Seats are limited to selected accounts. This invitation is non-transferable.
Axon Framework 4 reaches end of life on June 30, 2026.
Meet The Host : Martin Dilger
Author — Understanding Event Sourcing (2024)
The first book to unify Event Modeling, Event Sourcing, and Vertical Slice Architecture in one process.
Software Architect & Practitioner
Builds and advises on real production systems. His frameworks appear in Understanding Event Sourcing alongside Axoniq and are implementation-agnostic by design.
Endorsed by the field's defining voices
Including Adam Dymitruk (Adaptech Group) and Dr. Gabriel N. Schenker, who called the book "invaluable... influencing software development for years to come."
The Twenty-Minute Session
The real migration path: AF4 → AF5
Martin walks the architectural changes that actually matter in production: the shift to reactive-first, package restructuring, saga replacement with stateful event handlers, @EventTag requirements, and the new Configuration API. No fluff. Just the map
What teams get wrong
The migration pitfalls that documentation doesn't warn you about. Aggregate identity changes, silent test fixture failures, metadata propagation gaps, and saga serialization risks your team can avoid entirely.
AMA. Open floor.
This isn't Q&A moderated through a form. It's direct access to Martin's thinking. Bring your actual migration blockers, architecture decisions, or event modeling questions. He'll answer them plainly.

What Teams ask
What is the Axon Framework 4 end-of-life date, and what does it mean for my team?
Axon Framework 4 reaches official end of life on June 30, 2026. After that date, Axoniq will no longer issue security patches, bug fixes, or community support for any AF4 version. Teams still running AF4 in production after that date carry full operational and security risk without vendor recourse.
Who is Martin Dilger and why is he running this session?
Martin Dilger is a software architect and the author of Understanding Eventsourcing (2024)—the first book to combine Event Modeling, Event Sourcing, and Vertical Slice Architectures into a single consistent software development process. The book is available on Amazon and Leanpub, and has been endorsed by Adam Dymitruk (Adaptech Group) and Dr. Gabriel N. Schenker. His work in Event Modeling automation tooling has been credited as instrumental in accelerating industry adoption of the methodology. He is a practitioner first, working with Axoniq to help build critical systems in production.
Will this session be recorded?
No. There is no recording and no replay. This is an intentional choice: the AMA format only works when attendees ask their real questions rather than defaulting to passive viewing.
