I have to perform an upgrade from call manager 7.x to call manager 10.x. The 10x will be installed on new ucs server while the 7x is currently on the mcs box. The current install is business edition 7.x which includes call manager and unity connection. We would like to perform a backup of the current platform and restore on the new ucs server system, however how can this be accomplished?
