I don't have access to a luminous cluster at the moment, but I would try looking in the pg dump first. You could also try the crush map.
Worst case scenario you could set up a bunch of test clients and attempt to connect them to your cluster. You should be able to find which is the oldest version it allows. radosgw, ceph-fuse, or rbd-fuse from a given ceph version should tell you whether or not that version will work (choosing the package depending on what you use your cluster for). You can also check `ceph features` to see which features your currently connected clients support.
