[cisco-voip] replacing hardware in a production cluster

[Lelio Fulgenzi]

One of our tasks to do in preparation of our v9 upgrade is to swap in temporary hardware into our production cluster that runs v7 and remove hardware that runs both v7 and v9. We need to do this to two active subscribers and one subscriber that acts as our TFTP server. 

I have the time, so my plan is to replace the subscribers one at a time and wait for the dbreplication to complete properly before continuing to the next one. 

I have a couple of questions: 

    * I'm hoping that the dbrelication will initiate/complete once the server has been restarted after the DRS restore. Will I need to do anything special? 
    * Will phones attempt to register to the new subscriber before the DRS restore and dbreplication is completed? I want to ensure no phone interruptions. I'd rather not have to modify callmanager groups, etc. 


Thanks! 


Lelio
