Upgrading from 2.2.3 to 2.3.0

hi,

is a rolling update OK for upgrading from 2.2.3 to 2.3.0 ?

I tested with a single node setup, and it said

Legacy default stream has no connections, no migration needed.

So should it be OK just to add the elasticsearch_hosts line to the config file and then upgrade a multi-node setup one node at a time while running the other nodes?

Yes, this should be fine.
