Question about Percona XtraDB Cluster Upgrade

penguins_and_suchpenguins_and_such EntrantCurrent User Role Beginner
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 (https://www.percona.com/doc/percona-xtradb-cluster/5.6/upgrading_guide_55_56.html) 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!
