I've three servers with Debian 9, Maria 10.1 and running a Galera 
cluster.

We're upgrading the hardware by getting three new servers. They will 
have Debian 10 and Maria 10.3.

What are my options for accomplishing this with minimal service 
downtime?

One option I can think of
Using a mysqldump snapshot, set up Maria on one of the new servers to 
replicate as an asyncronous slave from one node of the existing 
cluster.Set up Maria on the two remaining new servers in a cluster with 
that async slave.When all looks good, migrate workload to the new 
cluster.
Does that seem reasonable?
