So I can stoptĀ  cephfs-data-scan, run the import, downgrade, and then reset the purge queue?

I suggest that you backup metadata pool so that in case of failure you can continue with data scan from where you stopped. I've read somewhere that backup must be done using rados export rather that cppool in order to keep omapkeys.

To late for that. Tried with cppool and failed...

Lucky man, I've been struggling with it for almost 2 weeks.
