Can graylog cluster works with different versions?


(Artem Davydov) #1

Hi , i have 2 node cluster with graylog 2.2.2 version. So i plan to update to 2.2.3 graylog server without downtime . Can graylog cluster works with 2.2.2 and 2.2.3 versions at the same time?

Yes, running different patch versions of Graylog 2.2.x in a cluster for performing a rolling upgrade is possible. Running different major and minor versions in a cluster are not supported.
