compatible version of UCCX to go to 11.5 with, but the 11.0.1.10000-75 was listed as a supported matrix.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">We recently attempted to upgrade UCCX 10.5 -- > 11.5. The deployment was HA, and we didn’t see much risk. The upgrade went fairly smooth, and we hit a finesse
bug which required the ECDSA COP file. While minor, it’s still not mentioned in the release notes.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">The real shocker was 4 hours later when the system stopped accepting calls and just handed out fast busys. Failing over to the secondary would fix the issue
for a few minutes, but then fast busy.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Our entire contact center, which is HA, was entirely down. Primary down, Secondary Down, and TAC was unable to resolve after hours and hours. It was a total
unmitigated Cisco disaster.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Rolling back fixed the problem. And then rolling forward again to 11.5 the system worked great again – but only for 4 hours. Then endless fast busys. We rolled
back and are on 10.5 working fine. But we are at a loss what could be causing this problem. Cisco TAC is in the same boat.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">If I had to guess, that seems like more of a licensing failure, because TAC even tried replacing our license. Anyone have a similar experience?<o:p></o:p></span></p>
