<div>Not sure which version you have but here is the Security Certificate Management chapter for version 10: <a href="http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/cucos/10_0_1/CUCM_BK_C2F2626C_00_cucm-os-admin-guide-100/CUCM_BK_C2F2626C_00_cucm-os-admin-guide-100_chapter_01101.html">http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/cucos/10_0_1/CUCM_BK_C2F2626C_00_cucm-os-admin-guide-100/CUCM_BK_C2F2626C_00_cucm-os-admin-guide-100_chapter_01101.html</a></div>

<div>Another good source is the CUCM certificate regeneration/renewal guide: <a href="http://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/200199-CUCM-Certificate-Regeneration-Renewal-Pr.html">http://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/200199-CUCM-Certificate-Regeneration-Renewal-Pr.html</a></div>

<div>Hello
<div><br>
</div>
<div>We run a cluster with 8 CUCM and 2 IM&P servers. On the IM&P servers are the following certificates about to expire and need to be renewed:</div>
<div>Tomcat</div>
<div>Tomcat-trust </div>
<div>Ipsec </div>
<div>IPSec-trust </div>
<div><br>
</div>
<div>I could not find a guide that describes how to renew these certificates. Does anyone know what the impact is when i renew these certificates and what services are impacted an need to be restarted.</div>
<div><br>
</div>
<div>Thanks a lot</div>
<div>Regards Reto </div>
