<p>Hi all,</p>
<p>I'm running a production stack on 3.3.3 with Three datacentres (one in my DMZ with two hosts with NFS, one in my DMZ on the engine host with local storage and one internal with NFS storage).</p>
<p>Could you point me in the direction of the upgrade instructions I should follow in order to go from where I am to where I need to be in terms of upgrading, and what downtime I might need to incur so I can plan it?</p>
<p>Thanks in advance,</p>
<p>Jim</p>
