Hi Moataz,<br><br>You may find this link interesting/beneficial<br><a href="http://www.ciscoknowledgenetwork.com/uc/">http://www.ciscoknowledgenetwork.com/uc/</a><br>There has been 1 webcast already and there are several upcoming regarding upgrading to CCM6.1. I think if you register you can view the previous webcast, it had some good overview info.<br>
<br>I would also chip in that if you can manage doing a server replacement style upgrade, give it some thought. It saved alot of downtime for us when we upgraded from 4.1 to 5.1.<br><br>Ed<br><br><div class="gmail_quote">
