Hi, I'd like to change the os to ubuntu 20.04.5 from my bare metal deployed octopus 15.2.14 on centos 8. On the first run I would go with octopus 15.2.17 just to not make big changes in the cluster. I've found couple of threads on the mailing list but those were containerized (like: Re: Upgrade/migrate host operating system for ceph nodes (CentOS/Rocky) or Re: Migrating CEPH OS looking for suggestions). Wonder what is the proper steps for this kind of migration? Do we need to start with mgr or mon or rgw or osd? Is it possible to reuse the osd with ceph-volume scan on the reinstalled machine? I'd stay with baremetal deployment and even maybe with octopus but I'm curious your advice.
