I have a ceph cluster in version 16.1.10 on Ubuntu not managed by cephadm.

I would like to upgrade it to 19.1.3 and to cephadm mode.

Please, can you advise me the best upgrade path?

IMHO the path would be to adapt the cluster to cephadm first and then let the orchestrator do the upgrades. https://docs.ceph.com/en/pacific/cephadm/adoption/ https://docs.ceph.com/en/pacific/cephadm/upgrade/ Regards -- Robert Sander Heinlein Consulting GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-43 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 220009 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin
