It is not possible to simply extend the expiry date of an existing HTTPS certificate. Instead you must replace the certificate with a new one.
However to maintain the security of your website you will want to replace the existing certificate before it expires. If you purchase a new certificate it will be valid from the date of issuance and you will effectively lose the remaining days on the current certificate.
To prevent the loss of these days it is possible renew a certificate up to 90 days before it expires. Renewing a certificate means you still order a new certificate but any remaining days on the existing certificate are added to the new certificate.
You can renew a certificate using any account. It does not need to be done using the same account. However the common name must be exactly the same.
