      That is  right. Usually newer clients would work with older
      servers but  3.6 saw a complete rewrite of AFR (afr-v2) which is
      not fully compatible with AFR-v1. It would be best to update the
      all the clients to 3.6 as well.<br>

                Gluster 3.4 server bits with 3.6 client bits should work
                fine. <br>
                <br>
                But I think the reserve (i.e. 3.6 server bits with older
                client bits) are not compatible because of below issues<br>
                <ul>
                  <li>Older clients can not mount the newly created
                    volume on 3.6 . This is because readdir-ahead will
                    be enabled on the volume by default which isn't
                    present in older clients.<br>
                  </li>
                  <li>We can't run rebalance on any volume created with
                    3.6 bits   ( with or without readdir-ahead) when
                    older clients are connected.  The rebalance command
                    will error out if older clients are connected.</li>
