The party line is to jump no more than 2 major releases at once. So that would be Octopus (15) to Quincy (17) to Reef (18). Squid (19) is due out soon, so you may want to pause at Quincy until Squid is released and has some runtime and maybe 19.2.1, then go straight to Squid from Quincy to save a step. If you can test the upgrades on a lab cluster first, so much the better. Be sure to read the release notes for every release in case there are specific additional actions or NBs. > On Apr 20, 2024, at 18:42, Malte Stroem <malte.stroem@xxxxxxxxx> wrote: > > Hello, > > we'd like to upgrade our cluster from the latest Ceph 15 to Ceph 18. > > It's running with cephadm. > > What's the right way to do it? > > Latest Ceph 15 to latest 16 and then to the latest 17 and then the latest 18? > > Does that work? > > Or is it possible to jump from the latest Ceph 16 to the latest Ceph 18? > > Latest Ceph 15 -> latest Ceph 16 -> latest Ceph 18. > > Best, > Malte > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
