Thanks Guillaume.

The doc says

Unless you use Incremental State Transfer, as you bring each node back online after an upgrade, it initiates a full State Snapshot Transfer, which can take a long time to process on larger databases and slower state transfer methods.

The wording suggests that it's up to me to choose IST. But isn't it the case that the server choses IST or SST, depending on whether galera.cache has enough writesets for an IST?

Can I upgrade a production cluster from 10.0.15 to 10.0.19 while the cluster remains in service, upgrading one node at a time?
