I was advised to comeup with a plan to change IP address of Call managers and Unity servers. We are moving to another Data Center with new subnet. (Planing a staging test)
I have two Call managers version 220.127.116.110 and two Unitys version 5.0.
Publisher and Subcriber and Primary/Backup Unity.
I was told to change the Unity IP addres first.
Please what is your expert advice?
pros and cons
Should I change the Unity first and why?
or CCM first and why? My last stop
