How to move an existing Let's Encrypt Certificate?

On behalf of @Mattias

My Nextcloud is running fine using the snap. A Let’s Encrypts Certificate was easily obtained with help of the nextcloud.enable-https script.

It’s for the moment a theoretical question, but I am curious nonetheless and want to be prepared for the day when I am in need of this information.

How to move and reuse an existing Let’s Encrypt Certificate from a snap to a new fresh nextcloud snap environment?

  • Use somehow the custom option of the nextcloud.enable-https script ?

  • Simply copy the certficiate data from var/snap/nextcloud/current/certs/certbot/config to the same folder at the new snap environment and run the nextcloud.enable-https script with the lets-encrypt option ?

  • Something else ?
