If you have capacity to have both online at the same
time, why not add the SSDs to the existing pool, let the cluster converge, then remove the
HDDs? Either all at once or incrementally? With care you’d have zero service impact. If
you want to change the replication strategy at the same time, that would be more complex.

can this be done on the fly and migration will just happen or do I need to
do something to move data?
I would actually like to relocate my object store to a new storage tier.
Is the best to:
1) create new pool on storage tier (SSD)
2) stop activity
3) rados cppool data to the new one.
4) rename the pool back into the "default.rgw.buckets.data" pool.
Done?
Thanks.
