Install Letsencrypt certificate on a new machine with already an existing certificate.

Hi,

I already have a site with an existing Letsencrypt certificate (a "plain" AWS ubuntu machine).

In the next days, I would like to migrate the site to a new machine (using Laravel Forge).

My question is, which steps should I follow to install the certificate on the new machine? Apart from change the domain's DNS.

Two options in mind:

1. Install the new certificate from the Laravel Forge panel (using "LetsEncrypt" option).
2. Use the option "Install Existing Certificate" (and copy paste the Private key and Certificate). Not sure if there will be problems with auto-renew.

Thanks!
