Galera Cluster 4 with MariaDB 10.4

Congratulations to Team MariaDB at MariaDB Corporation and MariaDB Foundation for releasing MariaDB 10.4.6 as Generally Available (GA) last week on 18 June 2019.

MariaDB Galera Cluster upgrade test results overview 10.3 -> 10.4

Recently MariaDB Galera Cluster 10.4.3 RC was announced – Galera MariaDB 10.4.3 RC

I would like to summarize overall reported issues related to Upgrade Tests from 10.3 version to 10.4.
In general we have 3 upgrade strategies:

* Provider upgrade – Upgrading only Galera
* Bulk upgrade – shut down all cluster and upgrade all nodes.
* Rolling Upgrade – Shut down nodes 1-by-1 and Upgrade sequentially.
