[cisco-voip] building lab CUCM cluster from production cluster [update] - FOLLOW UP

[Lelio Fulgenzi]

Just to follow up on this. Everything went well. There were a few other things I had to take care of, like some enterprise parameters and service parameters that had cluster name and ip addresses, etc. Also, CDR management and backup directory information. 


The biggest was ELM. ELM doesn't really use the IP address or hostname, but a registration/instance ID of sorts. Because I built the lab server from a DRS, it had the original registration/instance ID which ELM balked at. 


Running the following command on the server fixed things up: license client reset registration

updated to insert #7, changing hostname... 

I'm hoping to build a lab cluster from our production cluster. Here were the steps I was planning to take: 


    1. prepare offline network with DNS, NTP, SFTP servers 
    2. install CUCM v9.1 from disks, apply patch inline 
    3. restore publisher from backup 
    4. remove subscribers 
    5. remove bulk of phones (leave only test phones) 
    6. change publisher IP address 
    7. change publisher hostname 
    8. move publisher into online network 
    9. connect to license server 
    10. reconfigure features as required 


Are there any other configurations I should remove from the publisher while it's off-line? From what I gather, most communications is from the device to CUCM server. Are there any that are CUCM outbound depending on config? I'm thinking SIP trunks?
