Is it possible to migrate a legacy (i..e pre-Jewel) osd device that
was originally setup with dmcrypt keys in /etc/ceph/dmcrypt-keys to
use the newer osd-lockbox scheme without having to destroy the osd and
re-prepare it?
Thanks

You can do it manually by mimicing what ceph-disk does. It would be nice to have a tool to do that.

Can you elaborate - specifically what would I look for in ceph-disk?
I would be interested in writing the migration tool if I knew where to
start digging.
thanks!

The keyword to look for is lockbox, starting from here https://github.com/ceph/ceph/blob/master/src/ceph-disk/ceph_disk/main.py#L1193 looking at the pull requests that merged this, you should have some valuable context.
