I don't know where you got this information but it seems wrong. From previous history the last 2 LTS versions are supported (currently Firefly and Hammer). That would mean that Hammer should be supported until the L version is released. Infernalis should be supported until the release of Jewel. > If i follow the upgrade procedure there should not be any problems, right? So far we've upgraded every version without issues.

Usually you can upgrade LTS -> LTS, so you should be able to go from Hammer to Jewel. The same should be true to Infernalis. However minimum versions may apply (like you need at least version 0.94.4 to upgrade to infernalis). > > Also what is the correct order of upgrading? Mons first then OSDs? Usually mons, then osds and then mds and radosgw. But if there's something different it'll be published in the release notes. > > Any input on the matter would be greatly apreciated. If it was me, depending on what you value most: if you prefer stability and a conservative approach I'd install Hammer. If you prefer features and performance I'd install Infernalis. As an example all major players (like Redhat, Fujitsu, Suse, etc) use only the LTS versions for their distros. > > Thank you. > > > _______________________________________________ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
