Re-installing existing SUB on new server hardware

Hi,

I have to replace the hardware of an existing CCM4.3(1) subscriber by a new server hardware,keeping the software version same.

What are the steps involed?

How are the steps of installing a SUB for hardware replacement purpose different from a normal subscriber installation.

I am saying this, because the subscriber config details/entries already exist in PUB config database.

Do I need to do import of the subscriber(on new server h/w) after backing its database(from old server h/w).

Pls suggest.

Just use same hostname/ip address of old subscriber and continue with new installation

some customers prefer delete old subscribers and re-install new one from scratch but first option should work.

Hi Rajesh,

Just thought that I would throw this in to build upon the great info from my friend Gonz (+5 points Gonz - keep on posting!)

Procedure

--------------------------------------------------------------------------------

Step 1 Record all network configuration settings, including the computer name, network card speed and duplex settings, IP address, subnet mask, gateway, DNS, and WINS for the current system. Record the configuration of the servers in the existing cluster; record all software versions, Cisco CallManager services, coresident applications, and plugins, so you can reinstall them after the upgrade. Use Table 6-1 to record the information.

Step 2 Power off the Cisco Unified CallManager subscriber server and disconnect it from the network.

Step 3 Connect the new server to the network and power on the server.

Step 4 Using the Cisco-provided Operating System disks, install operating system 2003.1.1 (or later) on the new server that has no data on it.

--------------------------------------------------------------------------------

Caution During the operating system installation, make sure that you choose the New Installation or ***Server Replacement option.

Do not check the I am recovering a system from backup check box.

Do not join the server to a Windows Domain during the operating system installation. Joining the domain causes the Cisco Unified CallManager installation to fail.

--------------------------------------------------------------------------------

Step 5 Use Cisco Unified Communications Server Operating System OS Upgrade Disk that ships with Cisco Unified CallManager to upgrade the Cisco-provided operating system to version 2003.1.1. Before you perform the upgrade, be sure to read the operating system readme information that is posted on the operating system cryptographic software page. You can navigate to the site from the Cisco Unified CallManager software page at http://www.cisco.com/public/sw-center/sw-voice.shtml.

Step 6 Download and install the latest Cisco Unified Communications Server Operating System service release. The operating system service releases post on the voice products operating system cryptographic software page. You can navigate to the site from the Cisco Unified CallManager software page.

For installation instructions, refer to the file-specific readme document, Cisco Unified Communications Operating System, SQL Server, Security Updates, and Installing the Operating System on the Cisco Unified Communications Applications Server. To obtain the most recent version of these documents, go to http://www.cisco.com/public/sw-center/sw-voice.shtml.

Step 7 Download and install the latest OS-related security hotfixes, if any.

The operating system related security hotfixes post on the voice products operating system cryptographic software page. You can navigate to the site from the Cisco Unified CallManager software page.

For installation instructions, refer to the file-specific readme document, Cisco Unified Communications Operating System, SQL Server, Security Updates, and Installing the Operating System on the Cisco Unified Communications Applications Server. To obtain the most recent version of these documents, go to http://www.cisco.com/public/sw-center/sw-voice.shtml.

Step 8 Using the Cisco Unified CallManager Installation disks, perform a complete subscriber installation on the new server where you installed the operating system. Refer to the Cisco Unified CallManager installation document for more information. Go to http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/index.htm.
