SSL Wildcard Cert

Help
1

This is my first time using LetsEncrypt.

I have successfully managed to manually create a wildcard cert. and upload to an Azure Key-Vault and link the SSL cert. to an Azure Application Gateway - this all works.

certbot certonly --email dummy.name@xxx.net -d *.dummy_sub_domain.abdcdef.abc.uk --agree-tos --manual --force-interactive

openssl pkcs12 -inkey privkey.pem -in cert.pem -certfile chain.pem -export -out ssl_wildcard_dataservice.pfx

Also domain verification works OK.

Because the SSL cert. only has a short life before it needs to be renewed I now need to put in place an automated renewal - what I need to do is...

  1. Azure Key can be linked with 'DigiCert' which is where the company I work for already has an account.

  2. If this means purchasing the wildcard domain via Digicert this is fine.

My question is: as I manually creating the cert(wildcard domain) via LetsEncrypt do I need to some how un-register/delete the cert linked to the wildcard domain before I can register it with Digicert?

You can have all the certs you want at the same time. Each of them will be valid until they expire.
