Yes, updating a website using HTTP instead of HTTPS is important. For starters, HTTPS is extremely useful in solving data protection issues. Moreover, websites that handle bank transactions, e-commerce business, and user data should update to the latest HTTPS format. This way, they can protect the user's data from getting hacked by an unwanted third party. Additionally, if a particular website doesn't have a valid SSL certification, the browser will immediately detect this as an error. As such, you will notice the error message displayed on the screen as "connection is not secure." Hence, it is very important to establish a website with the proper secure connection using the correct security configurations.
