Steps to update Sitecore SSL certificates (Sitecore XP 9.3)

 It's a general requirement to update the security certificates for the website.

It's more enjoyable when we work on the Sitecore, consider multiple endpoints like CMS, xConnect, Identity servers and XC Roles. I again got a requirement to update the certificates and wanted to share this with the community so everyone can quickly do this without any issue or hurdles.

So let's get started the journey to update the certificate :) 

Steps  1 - Open the mmc.exe

 Àdd certification--> computer account

Install your certificate and you will see your certificate here-

Copy the thumbprint of the installed certificate 

Copy the thumbprint of the installed certificate and keep in a file.

Now, got to certificate and add all application pools identifier.

Make sure you enter the name in   IIS AppPool\App Pool identifier name format otherwise you wouldn't get the identifier.

Now, Search for the existing thumbprint on the site, You will find in below files.

1. Identityserver\Config\production\Sitecore.IdentityServer.Host.xml
2. CMsite\App_Config\ConnectionStrings.config
3. xconnect\App_Config\AppSettings.config
4. xconnect\App_Data\jobs\continuous\ProcessingEngine\App_Config\ConnectionStrings.config
5. xconnect\App_Data\jobs\continuous\AutomationEngine\App_Config\ConnectionStrings.config

After replacing the file, got to IIS site and choose the correct certificate and restart the IIS.

that's it, It's very straightforward.

Troubleshooting - 

1. I got this error after updating the SSL certificate.

Fix - I missed to include the identifier role in the certificate, After including that role this issue got resolved,
