The subscription cannot be found.

I have installed 3cx on premise and the license expires on 2024-12-17, now I want to renew or upgrade to Pro 16 calls. But when I access the portal, I no longer see the previously installed system, I get a message "The subscription cannot be found." when renewing, so can I add a new system and then upgrade the license, then replace the current expired license?

Your old free licence is allready deleted. You can buy a new licence and change your key on your system if its at least on v18 u9a (build35).
