As I’v read and thought a lot about the migration as this is a bigger
project, I was wondering if anyone has done that already and might share
some notes or playbooks, because in all readings there where some parts
missing or miss understandable to me.
I do have some different approaches in mind, so may be you have some
suggestions or hints.
I think I will update the el7 nodes to el9 with nautilus. It seems possible to build the
nautilus rpms for el9. After that upgrading ceph. This will prevent having to upgrade the
nodes 2 times.
