Richard Janík created WFLY-9877: ----------------------------------- Summary: NAKACK, UNICAST2 and MERGE2 need to translate to their newer variants Key: WFLY-9877 URL: https://issues.jboss.org/browse/WFLY-9877 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 12.0.0.Beta1 Reporter: Richard Janík Assignee: Paul Ferraro This is only an issue for EAP, which has different versions than WFLY, for that reason, all the versions mentioned here are EAP ones. After some discussion with people who test migrations, we found out that these protocols need to be translated to: {noformat} NAKACK --> NAKACK3 NAKACK2 --> NAKACK3 (already done) UNICAST2 --> UNICAST3 MERGE2 --> MERGE3 {noformat} These are not in the default 7.0 or 7.1 configuration, so why do we need to translate these like we do it for NAKACK2? Because these protocols can be expected to be present in the 7.1 configuration due to migration from 6.x, where they are by default. Since, after migration from 6.x, these will work with the 7.1 configuration, and since there is a reason to expect them being used even if they are deprecated, we should not just silently remove these protocols with the JGroups upgrade that is in 7.2 - the configuration file from 7.1 should always work with 7.2.
