The new CCM servers are up and running with version 9.1.2, and the phones work.
Phones reconfigured to talk with the new CUCM and upgraded with new ios
The old 7940 phones did not have an upgrade
DNS entries corrected for both CUCM boxes.
DHCP Scopes all change (phones would not have configured without this)
Informacast is registered with CCM but is not discovering the phones. JTAPI issue?
Attendant Console looks to be registered we need to test on Monday
Routers working as expected
All but ~20 phones have re-registered those will need to be addressed on Monday
CER is having a strange licensing issue, we have a TAC open and will reconnect with the engineer in the morning
Exchange and Lync seem to be working properly
All in all a lot accomplished in one evening
Big thanks to Kevin and Nelson.
