Hello to every one....
I'm a data guy and bit of experiences in voice.
Currently i have cucm 5.0 running on MCS7825 now we plan to go cucm 9.X in new server with old backup. After 9.x installed in new box, old backup can fit and runn without any manual configurations? (dial plan, phone css & partition DP,region....)
Before pushing the back up what are all things i need to look in too.
