Migrate volume from Red Hat Storage Server 3.0 Update 1 cluster to Glusterfs 3.10 opensource cluster

Hi everybody,

We have 6 x Red Hat Storage Server 3.0 Update 1/ gluster servers in a cluster on RHEL 6.8 They run Gluster version 3.6

My task
I have to migrate several volumes to glusterfs community 3.10 or 3.8 on a new cluster.
I have to keep the Red Hat Storage Server cluster available because this won't be decommissioned.

Can I do this
Add a glusterfs server running 3.8 or 3.10 to the Redhat Storage Server 3.0/Update1 cluster.
Migrate the volume to the new server.
Remove the server from the old cluster.
Add the server back into the 3.10/3.8 cluster

Is this possible and does any body have any advice when mixing gluster versions on servers?

These RPMs are installed on Red Hat Storage Server 3.0 Update 1
