Dear lustre experts.

Whats is the best way to migrate a MGS device to ZFS? Copy the CONFIGS/filesystem_name-* files from the old ldiskfs device to the new ZFS MGS device?

Currently we have a combined MDT/MGT under ldiskfs with lustre 2.10.4. 

We want to upgrade to lustre 2.12.0 and then separate the combined MDT/MGT and migrate MDT and MGT to separate ZFS devices. 

Regards.
