Hi Rob and Java,

Thank you for both fruitful details. However i dont understand rob stated on this sentences. ---> The upgrade to this SR would buy you time to start down the path towards CUCM 7.1(x) which is the new "gold" standard.

Currently we are running 1 publisher and 2 subscriber in ccm 4.1(3)sr5d . Can i direct install the sr7 or sr8a intallation file ?

This document got mentioned properly ? http://www.cisco.com/web/software/282074220/23393/ciscocm.4-1-3-sr8a-Readme.pdf

Please advise.

Thanks.

Hi Fung,

The reason I said "The upgrade to this SR would buy you time to start down the path towards CUCM 7.1(x) which is the new "gold" standard." is that CCM 4.1 will only be supported until May 2011 which is fast approaching :) You will need to upgrade to a "new" version like CUCM 7.x at some point is time as there will be no more CCM 4.1(3) releases or support from Cisco.

CCM 4.1(3)sr8a is the last/latest release for the 4.1(3) train. It will contain the most Bug fixes and patches and also contain support for the newest IP Phone models.

Here is the note from the ReadMe that states the upgrade path;

"This SR is based on Engineering Special 144. For this Service Release, Cisco supports upgrades from any Cisco Unified CallManager 4.1(3) release up to 4.1(3)ES144."

Hope this helps!

Hi Rob,

Thank you for your reply, That's means, We can upgrade the ccm 4.1(3)sr5d to sr8a by simply install it by downloading the installation file. Just double click the .exe file , starting from publisher and follow by subscriber. It will be ccm 4.1(3)sr8a.

Thanks for the confirmation.

Hi Fung,

You are most welcome my friend :)

Installation Instructions:

The following procedure provides details about how to install Cisco Unified CallManager 4.1(3)SR8a.

Note: Cisco recommends that you apply this Service Release during a maintenance window.

Note: It is very important to disable platform agents and services, such as NetIQ and Prognosis performance monitoring, antivirus (such as Cisco-verified McAfee services or other Cisco-verified AV products) and intrusion detection software, remote management services, and any other monitoring applications that automatically restart services; this action ensures that your system does not encounter issues that are associated with these services.

This Service Release upgrades the affected services and files and then it restarts the server when the upgrade has completed successfully.

Apply this Service Release to all of your Cisco Unified CallManager servers, beginning with the publisher server and TFTP server.

Installation Procedure

Note: To verify that the installation completed successfully, follow the instructions in Step 6 below.

Perform the following procedure to install Cisco Unified CallManager 4.1(3)SR8a:

1. From the Voice Software Download Center, navigate to Cisco Unified CallManager version 4.1 and locate the ciscocm.4-1-3-SR8a.exe file; then, follow the instructions to download the file.

2. Transfer the file to each CallManager node in the cluster.

3. Double-click the ciscocm.4-1-3-SR8a.exe executable file to begin the installation as noted below:

4. Cisco recommends that you upgrade all servers in the cluster sequentially, to the same version of Cisco Unified CallManager software; otherwise call-processing interruptions may occur:

a. Begin with the publisher server

b. Followed by the TFTP server

c. Followed by the sequential upgrade of the backup servers

d. Finally, the sequential upgrade of the primary servers

5. Click Next when the installation process displays a message that asks if you want to install this SR. The remainder of the installation process continues without any additional user input. The system displays a message when the installation is complete.

6. Verify that the installation completed successfully by taking the following actions:

a. Click Yes when the system prompts you to view the log file.

b. Scroll down to the end of the log file; if errors occurred during the installation, the errors section at the bottom of the log file will be updated with a corresponding severity.

7. If any of the Client Plugins have a lower version than those included in this SR, perform the following:

After you have rebooted the server and completed the upgrade on all servers in the cluster, go to Cisco Unified CallManager Administration on any client machines (i.e. JTAPI, RTMT Client, etc.), navigate to the Application > Install Plugins menu. Choose the applicable plug-in, run the program from its current location, and follow the installation instructions that the system displays.

8. The system may create or edit the following log files during the installation or uninstallation process:

c:\program files\common files\cisco\logs\CCMPatch\Cisco CallManager 4.1(3)SR8a Installation YYYY-MM-DD HH.mm.log (this file is also accessible by navigating to the Start menu shortcut "Cisco Install Logs" under the CCMPatch folder)

c:\install\dbinstall\dbinstallXXX.txt

c:\program files\common files\cisco\logs\CCMPatch\sqlX.txt

c:\program files\common files\cisco\logs\history.log

Note: This Service Release can take up to 20 minutes to complete the installation.

Hope this helps!
