[cisco-voip] Migrating from v7 to v9 (same cluster IPs) - getting phones to recognize new v9 cluster

[Lelio Fulgenzi]

So, still planning our v7 to v9 migration. The last time we did this, we went from v4 to v7 and changed the IP addresses of the servers. To ensure phones would go that way, we applied an ACL which blocked access to the servers, which forced a DHCP and they brought down the new TFTP address and voila, things went well. 

I was thinking of doing something similar during my migration to v9. In my testing of the ACLs though (still on v7), I noticed that the phones are not really bringing down a new copy of their configuration, just re-registering. 

I still have to test how phones behave when I complete the process, i.e. block ACL, unplug v7, plug in v9, allow ACL. 

Will the server and phone communication be sufficient to tell the phones to download a brand new configuration file? 

What have others done to migrate their phones from v7 to v9 when using the same cluster IPs?
