Ubuntu 16.04 reaches End-Of-Life soon on 30 April 2021 and it will enter the Extended Security Maintenance (ESM).
ESM is a program by Canonical for companies that want to continue to use old OS distros and to remain secure.
Reaching EOL for Ubuntu 16.04 means that there will be no more maintenance or security updates which is crucial for your business and/or application.
Okay, what are my options?
Running on an outdated and not supported operating system is strictly not recommended. And having this in mind, your only option is to migrate to a newer Ubuntu release (18.04 or 20.04). There are two approaches to how you can upgrade to the newer versions of Ubuntu.
The first one is to buy a new VPS or Dedicated Server with a newer version of Ubuntu. Then, you have to configure your applications and migrate your data from the old to the new server. Afterwards, you can swap the IP addresses, and you are migrated to the new Ubuntu.
The second approach is to actually upgrade your existing setup. It is probably the easiest and cheapest option, but we have to be sure that we can allow some downtime and we have to create a backup before we start. If you want to upgrade to Ubuntu 20.04, you have to go through Ubuntu 18.04 LTS (Bionic Beaver) and then to Ubuntu 20.04.
NOTE: The second method is not applicable for OpenVZ-based VPS.
How to upgrade from Ubuntu 16.04 to 18.04?

How to upgrade from Ubuntu 18.04 to Ubuntu 20.04?
Upgrading to Ubuntu 20.04 from Ubuntu 18.04 is similar, just run this command:

What happens if I remain using Ubuntu 16.04?
It is not recommended. This will leave you at risk to:
Software incompatibility, etc.
We strongly advise you to upgrade to a newer version of Ubuntu.

The other Ubuntu versions will have support as follows:
- Ubuntu 18.04 up to April 2023;
