Upgrading CertBot

I have a Ubuntu 16.04 server that runs a old V1 (certbot 0.22.2) of letsencrypt. If I were to follow the instructions on installing the latest version of CertBot here:

  1. Removing the old client will not stop them from working, right?
  2. Running the new Certbot will just overwrite old certificates and just work, right?

My web server is (include version):
Ubuntu 16.04.6

The operating system my web server runs on is (include version):

I can login to a root shell on my machine (yes or no, or I don’t know):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):
certbot 0.22.2

That’s correct. Your certificates are stored in /etc/letsencrypt, and even if you uninstall Certbot, those files will be preserved.

If you are nervous about it anyway, you can perform a backup of that directory.

It will just keep using your existing configuration - nothing will be overwritten.
