I have a 10.1 install of galera cluster running in master master mode, i
would like to upgrade to 10.2.9, and have seen the instructions here[1]
about "regular" updates, but i'd like to keep the cluster online while i
upgrade.  Is there any difference or things to look out for to keep data
consistency.  can a 10.2 node replicate to a 10.1 node (my guess would be
no due to the new fields after mysql_upgrade)  Downtime offline is a
possibility, but i'd like to avoid it, as would anyone.

Any hints/links are greatly appreciated.
Jeff
