How to update to ACME v2 with old certbot installation

I used certbot to install SSL on my Ubuntu 14 server running Nginx & PHP about 2 yrs ago and I recently got an email (refer to excerpt below) that mentioned I have to update my software to use ACME v2 protocol. How do I do this using certbot? do I have to update certbot software first?

According to our records, the software client you’re using to get Let’s
Encrypt TLS/SSL certificates issued or renewed at least one HTTPS certificate
in the past two weeks using the ACMEv1 protocol. Here are the details of one
recent ACMEv1 request from each of your account(s)

Hi @mrlami

Ubuntu 14 is EOL, so updating Certbot may not work.

What says

certbot --version

Check

there is an option to use --server with the ACME-v2 url. If your certbot is new enough, that may work.

If your certbot is too old and if it isn’t possible to update your Ubuntu, perhaps check another client, may be acme.sh.
