Hi,
I have CUCM7.0.0.39771-4 and want to upgrade with the image downloaded from CCO (UCSInstall_UCOS_ES_7.0.1.21007-1.sgn.iso) but I have error message 'No valid upgrade options were found' when I click <Next> button on the upgrade screen.
No readme file available for 7.0.1. please guide me what's problem on me.
Advise please,
