My RapidSSL Certificate is about to expire and I need to renew it. From what I understand, I can use the existing signature (less secure) or generate a new request. In either case, once I install the new key, is there any chance that browsers will display a warning or error message to users saying that the SSL cert has changed?
Also, I have some automated programs that SFTP information to my server every morning. Will they get a message that the server's signature has changed and manually need to accept?
Thanks
