Hi team

Any blog or steps what a dba should do when upgrading OS?

Rhel 9.6 to 9.7 in one server and one from 9.5 to 10.x

3 node ha set up 
Postgres 17.6
Patroni 4.1.0
Pgbackrest 2.56

It's only major-version OS upgrades (8->9, 9->10, etc) that cause issues.

Are these in-place upgrades from RHEL 9->10, or is it going to new servers?
