Gluster users - Jan 2018 - Roll back glusterfs to 3.10

Hi,
I want to roll back a distributed replicated cluster from 3.12 to 3.10
because of performance issues which appeared after upgrade.
But I didn't find any docs which could help me.
Is it even possible?

Ok, I've got the plan:
1. unmount volume on all clients
2. shut down glusterd on all nodes
3. set old op.version (310xx) via /var/lib/glusterd/glusterd.info on all
nodes
4. downgrade rpm packages everywhere
5. start glusterd & mount volume

Does it look fine?
Also is there any way to roll back without downtime?

Thanks.
