your phone firmware and upgrade to the current version before the cutover or all your phones will have to upgrade on cutover.<o:p></o:p></span></a></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Also make sure you don’t change Hostname/Ip addresses in the sandbox as that will cause your ITL to regenerate and cause issues with phone configuration changes
after cutover.<o:p></o:p></span></p>
