Yeah.

That's right. Upgrading won't erase your certificates or configuration, and everything should keep working as before.

Yes. The Certbot package includes a systemd timer and cron job. (The latter will disable itself since you're using systemd.)

If your current cron job includes other options (like a hook to reload a mail server) you'll have to do something about configuring that, though.

For what it's worth, the Certbot package keeps `/usr/bin/letsencrypt`. (Replacing it with a symlink to `/usr/bin/certbot`.) So you can start running "`certbot`", but your old "`letsencrypt`" workflow won't stop working.

You can run "`certbot renew --dry-run`" to test renewing still works.
