This is exactly what i would like to archieve but is not possible.
I am not sure I understand what isn't possible.
Install the new version of Gluster on a new server or reuse an existing
server. Set it up as a new Gluster instance (not part of the existing
one). Migrate all of your VMs to it. When they are all migrated,
upgrade the remaining servers and bring them into the new Gluster instance.
Depending on your VM infrastructure, you might be able to do this with
no downtime, otherwise each VM will be down for the amount of time it
takes to migrate, but you aren't taking down the entire Gluster
infrastructure which is what you have mentioned.
