I guess you could upgrade each node one by one. So upgrade/reinstall the OS, install Ceph 15 and re-initialise the OSDs if necessary. Though it would be nice if there was a way to re-integrate the OSDs from the previous installation... Personally, I'm planning to wait for a while to upgrade to Ceph 15, not in the least because it's not convenient to do stuff like OS upgrades from home ;-) Currently we're running ubuntu 18.04 on the ceph nodes, I'd like to upgrade to ubuntu 20.04 and then to ceph 15.
