Howdy,
I’m preparing to update an existing (production) Percona XtraDB Cluster (3 nodes). This will be a point release upgrade, going from 5.6.24-72.2 → 5.6.32-25.17.
This will be the first time upgrading a production cluster. I’ve read this document ([url]Percona XtraDB Cluster) but I’m thinking I don’t have to do that because this is just a point release upgrade. Not a major upgrade (like 5.5 → 5.6).
My question is:
I hope to pull one node out of the cluster, update the mysql binaries and then add it back in without issue. Is this possible? Can I have a cluster with one member on 5.6.32.25.17 when the other two nodes are running 5.6.24.72.2-56
Thanks!
