Automated Testing of the upgrade process is often overlooked or even not existed in practice to some organizations or companies that are managing their PXC/MariaDB Galera Cluster. In this blog, we emphasize the importance of this and how it can be drastic and risky if the DBAs and your technical team just do their own thing without adhering to the industry standards and performing best practices while upgrading your PXC/MariaDB Galera Clusters.

The way Galera Cluster works is that it handles schema changes in a specific manner. It is possible to execute a schema change on a single node in the cluster, but it is tricky.
