I have uccx cert expiring soon and I need to find out the steps to regenerate/renew below certs. I already renew CUCM certs by using below steps, but not sure if I need to use same doc to regenerate UCCX certs?

>intelligencecenter-srvr.jms.pem

CUCM Versions 8.X > - Certificate Regeneration/Deletion

Note:
* When regenerating certificates, be advised that this action should be performed after hours due
to the requirement of restarting services and rebooting phones in the cluster.
** Monitoring Phone Registration via RTMT tool is highly recommended.
*** It is recommended that you reboot ALL phones prior to Certificate Regeneration in order for
all phones to have the latest ITL – and may help identify phones with current ITL issues.
Monitoring Endpoints
Real Time Monitoring Tool (RTMT)
 Login to the publisher using RTMT
o Select the Voice/Video Tab
o Select Device Summary
 Here you will see the total number of registered end-points and how many to each
node.
 Please monitor during endpoint resets to ensure registration prior to moving to next
certificate.
……….
Is your Cluster in Mixed Mode?
 System > Enterprise Parameters
To regenerate expiring or expired certificates please follow the procedures below.
Tomcat Certificate:
Identify if you are using a third party certificates.
1) Log into Cisco Unified OS Administration Page

b) Once open Click “Regenerate” Wait until you see “Success” then close pop-up or go back to “Find/List”.
4) Continue with subsequent Subscribers; following the same procedure in step 2 thru 3 and complete on all subscribers in your cluster
5) After all Nodes have regenerated the tomcat certificate, restart the tomcat service on all the nodes beginning with the publisher then followed by the subscribers.
a) To restart tomcat you will need to open a CLI to each node and enter the following command, "utils service restart Cisco Tomcat".
IPSEC Certificate:
Note:
IPSEC certificates will affect the DRF master and local which deals with backup and restore.

for Cluster Secure Mode. If the value if 0, the cluster is not in mixed-mode. If it is “1”, the cluster
is in mixed-mode and you will need to update the CTL file. Ensure you complete this section

Identify the expired or certificates no longer required for your system. Base Certificates cannot be
deleted (i.e. CallMananger, IPSEC, Tomcat, CAPF, TVS). Any trust certificate can be deleted. Follow
procedures below.
1) Log into Call Manager Publisher – Cisco Unified Serviceability page
a. Tools > Control Center – Network Services
i. From the drop down select the CUCM Publisher
ii. Stop Certificate Change Notification
iii. Repeat for every Call Manager node in your cluster
iv. If you have an Instant Message and Presence (IMP/CUPS) Server
v. Stop Platform Administration Web Services
2) Open a GUI to each sever and log into Unified OS Administration page (ALL Servers Same Time)
a. Navigate to Security - Certificate management – All Servers
b. Find the expired *-trust certificates. (10.0 and higher you can filter by Expiration. Below
10.0 you will need to identify the specific certificates manually – or via the RTMT alerts if
received)
c. You may see the same trust certificate in multiple nodes. It must be deleted individually
from each node.
d. Select the trust certificate to be deleted (depending on your version you will either get a
pop-up or you will be navigated to the certificate on same page)
