Currently: One cluster with 7825 (pub) and 7825 (sub).
Target: One cluster with DL-380(pub) and 7825 (1st sub) and 7825 (2nd sub).
This would ordinarily be straightforward, but I need to give the new Publisher a new name and new IP. If I build the new Publisher and restore config while the existing pub and sub continue on the network, would I be able to kill the old publisher (shut down or disconnect the Ethernet) and then have the existing Subscriber accept the new Publisher? Anybody done this?
Yeah, that's what I was trying to avoid. Has anyone come up with a comprehensive list of steps necessary to successfully CHANGE the name of a server? This is a long-standing limitation; by now I imagine someone with a strong motivation has done it. . . . ?
I have had many customers that have attempt that and at the end they ended up rebuilding the servers since it is completely not supported to change the hostname, if you do this you will have many problems trust me...
I wouldn't consider trying it unless I knew 100% it would work. I went through this two years ago while staging a server. After everything was built and phones BAT'd in, we found the IP provided to us was wrong and would not work in the customer environment. Had to completely rebuild.
Now I need to do it because the Publisher will live in a new facility and we want to move it and keep local naming standards.
Cisco Product Managers: Note JBARCENA's comment that "many customers" want and need to do this! It's time for a Cisco-approved method!!
