<div><div><p>Hi All,</p>
<p> It appears a rolling node by node upgrade of a protocols cluster is not possible. Ctdb is the sticking point as it won\u2019t run with 2 different versions at the same time. Are there any plans to address this and make it a real Enterprise product?</p>
<p> </p>
<p>Cheers,</p>
<p> </p>
