Please be more specific what you mean :-) Versions are compatible, sure.
If you change the wire format, then it's of course not. If old nodes send java serialized messages, and you disable it on one node, it of course won't deserialize them - that is kind of the point. If your old nodes already use enable-additional-serialization-bindings then such rollout would work, since both sides use protobuf anyway always anyway. -- Konrad `ktoso` Malawski Akka <http://akka.io> @ Lightbend <http://lightbend.com> On 13 February 2017 at 13:50:41, Bert Robben ([email protected]) wrote: Given I have a cluster running Akka version 2.4.16 (using various Akka distributed features such as sharding, cluster singleton, remote actor creation, etc). Would it be possible to do a rolling upgrade of the cluster and gradually upgrade all nodes to 2.4.17 ? >From http://akka.io/news/2017/02/10/akka-2.4.17-released.html, its clear that this change is compatible, but it's not clear if that also means you can have half a cluster with the old version and the other half with the new version. thanks, Bert -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
