replacing subscriber with the new one with same IP adress and hostname

Hi all,

CUCM 9.1.2

We have a faulty subscriber ( causes code yellow alarm when there is a high load)   on CUCM cluster and tomorrow we want to replace this sub with a new server.

WE will install new server with the existing hostname and Ip adress.

My question is, do we need to delete ITL files on phones when new subsc. is  on live? Do the phones get stuck when trying to connect to new sub?

Regards.

No, there should not be any issue related to ITL files.

Hope you will follow below procedure to replace it.


    Step 1   Gather the necessary information about the old server.
    Step 2   If you are getting the system time from an NTP server, verify that the publisher node can synchronize with the NTP server before you install a subsequent node.
    Step 3   Shut down and turn off the old server.
    Step 4   Connect the new server.
    Step 5   Install the same Cisco Unified Communications Manager release on the new server that was installed on the old server, including any Engineering Special releases. Configure the new server to use the same configuration information as the old server.
    Step 6   Restore backed up data to the node by using DRS.
    Step 7   Reboot the new server.
    Step 8   Verify that the new server has the same number and status for all Critical services that you gathered before replacing the server.
    Step 9   Verify that the db Replicate state has a value of 2. This indicates that the database is set up on this node.
    Step 10   Perform the post-replacement tasks.
