@pjfanning There two missing pieces left: 1. Deserialization of Akka cluster messages. I created the PR for this one #1578 2. Supporting Akka config for JoinConfigCompatChecker. An exception is thrown [here](https://github.com/apache/pekko/blob/main/cluster/src/main/scala/org/apache/pekko/cluster/JoinConfigCompatCheckCluster.scala#L40-L42), when a Pekko node tries to find the downing path in the Akka config. I solved it by simply checking if the path exists in the config before doing the comparison. ``` val downingProviderResult = { if (toCheck.hasPath(DowningProviderPath) && actualConfig.hasPath(DowningProviderPath)) JoinConfigCompatChecker.checkEquality(List(DowningProviderPath), toCheck, actualConfig) else Invalid(im.Seq("Downing path not found. Set configuration-compatibility-check.enforce-on-join to off to enable cluster joining.")) } ``` While this all that's necessary for the rolling upgrade support, I tried to find a better approach for the second problem. See this [commit](https://github.com/sadekmunawar/pekko/commit/60f208f7c9690c98356466094ec97516cc0f8230). I haven't had the chance to integration test this approach, yet. It should fix the exception issue, but it likely sends configs with Pekko paths to Akka nodes [here](https://github.com/sadekmunawar/pekko/commit/60f208f7c9690c98356466094ec97516cc0f8230#diff-93928721f2ceeb4acf73b9c1582977f8c1157feefbf64e6d5f8a694e5ae40a5aR647-R654) -- This is an automated message from the Apache Git Service.
