Ceph jewel to luminous upgrade

[AlexanderTitov]

We are planning to upgrade the ceph cluster from jewel to luminous using this guide https://pve.proxmox.com/wiki/Ceph_Jewel_to_Luminous
Is there any rollback plan possible for this upgrade?

No, at least I'm not aware of any rollback solution in this context, besides the usual "backup backup backup" strategy.
