I'm upgrading CUPS 126.96.36.19900-13 to 188.8.131.5200-36 which I have downloaded from CCO.
I restarted the server and when I apply switch version command from CLI to swtich to ver 7, it doesn't do anything.
Has any body experience this kind of issue? This is a standalone lab installation so physically there's no CUCM connected. I have restored production CUPS backup on it and wants to upgrade to ver 7.
Thanks in advance,
