How to transfer the installed certificate to a new computer

I will have a new PC in the next week
so how can i transfer the installed certificate to the new one?
any extra steps besides backup the configuration and the certificate file are needed?
thanks & regards

You don't need to do anything special.

Just backup your configuration on the old machine and then, when you're ready, uninstall Opus.

Install Opus on the new machine, give it your certificate and restore your configuration backup.
