I currently have a letsencrypt cert from the official client for my domain. For a variety of reasons, I’m considering changing to use letsencrypt.sh for future renewals. It does provide a facility to import the account private key, but the directory structure is different enough that it’d be simpler to just start over.
This leads to the question: If I’ve created a certificate for a domain using one account on the CA, will it cause any problems if I later try to create a certificate for the same domain using a different CA account? I think the question is related to What happens if you don’t back-up account info?, but not quite the same.
