  <p>
   As part of a provisioning approach you can use MySQL Enterprise Backup to copy and
        restore the data from a group member to new members. However you
        cannot use this technique to directly restore a backup taken
        from a member running an older version of MySQL to a member
        running a newer version of MySQL. The solution is to restore the
        backup to a new server instance which is running the same
        version of MySQL as the member which the backup was taken from,
        and then upgrade the instance. This process consists of:
  </p>
  <div class="itemizedlist">
   <ul class="itemizedlist" style="list-style-type: disc; ">
    <li class="listitem">
     <p>
      Take a backup from a member of the older group using
      <span class="command">
       <strong>
        mysqlbackup
       </strong>
      </span>
      . See
      <a class="xref" href="group-replication-enterprise-backup.html" title="20.5.6 Using MySQL Enterprise Backup with Group Replication">

      </a>
      .
     </p>
    </li>
    <li class="listitem">
     <p>
      Deploy a new server instance, which must be running the same
            version of MySQL as the older member where the backup was
            taken.
     </p>
    </li>
    <li class="listitem">
     <p>
      Restore the backup from the older member to the new instance
            using
      <span class="command">
       <strong>
        mysqlbackup
       </strong>
      </span>
      .

    </li>
    <li class="listitem">

      Upgrade MySQL on the new instance, see

   Repeat this process to create a suitable number of new
        instances, for example to be able to handle a failover. Then
        join the instances to a group based on the
