Galera cluster consisting of more than one Linux distro?
Is it possible/supported to run a galeracluster, (MariaDB10.2) where exisiting 3nodes is running on one distro Linux, and then add 3nodes using another distro to the mix, before finally removing the old 3 nodes distro?
(Ubuntu migrate to CentOS, to be specific)

There should be no reason why not, all else being equal.
(And I can now vouch that this *is* a correct assumption.I just managed to set up another three additional nodes, all running Centos7 (1804?) and they are doing SST just fine from the exsiting Ubuntu16.04.
All is MariaDB 10.2 - so a transparent switch from Ubuntu to Centos (or whatever distro) is possible. That's kinda cool!
