Rolling Updates and Versions

Pekko upgrades

Pekko supports rolling updates between two consecutive patch versions unless an exception is mentioned on this page. For example updating from 2.5.15 to 2.5.16. Many times it is also possible to skip several versions and exceptions to that are also described here. For example it’s possible to update from 2.5.14 to 2.5.16 without intermediate 2.5.15.

It’s not supported to have a cluster with more than two different versions. Roll out the first update completely before starting next update.
