SharePoint 2016 server certificate expiration - Renewal

Question

We have a SharePoint 2016 server farm with one front end, one application, and one Office Online server. On these servers, we have a wild card certificate that is going to expire in a few days. Before that, we want to update the new certificate in these servers. Could anyone please provide me with the end-to-end process to update the certificate on the SharePoint 2016 server?

Here're steps for you:

1.Obtain new SSL certificate from a Trusted Certificate authority or create a new self-signed SSL certificate from IIS.

2.Import self-signed SSL certificate to SharePoint Certificate store. Open Manage Compute Certificate -> SharePoint node -> Right click All tasks -> Import new SSL certificate.

3.Go to Central Administration -> Security -> Manage Trust -> New.

4.Go to IIS -> Select the web application, click Bindings in the Actions pane -> Choose the https binding -> Choose new SSL certificate.

5.Configure AAM. Go Central Administration -> System Settings -> Configure alternate access mapping -> Choose the web application -> Edit Public URLs, then add new HTTPS URL.
