Hi.

After reading the documentation it is not clear for me, how upgrade and downgrade processes should be performed over the solution. Could you please describe somewhere in the documentation:

• How to upgrade OpenEBS to the newer version (hopefully with no downtime). Now it is not clear, does it provide zero-downtime guarantees or not
• How to downgrade OpenEBS to the older version (hopefully with no downtime)
• Maybe some compatibility policies and notes between versions

Thanks in advance!
