Update xConnect Certificate in Sitecore Scaled Environment

Recently I have changed the xConnnect certificate for my client, so here are some steps and troubleshooting steps that I have followed for a scaled environment.

Install certificate

• Double click on your xConnect xxx.xconnect_client.pfx certificate.
• Select Local Machine and click on Next.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
• Enter your password and click on Next.
  
  
  
• Select “Place all certificates….” And click on browse and select Personal.
  
  
  
  
• Click on Finish.
  
  
  
  
  
  
  

Allow AppPool access to the certificate

• Go to the certificate and right-click.
• Go to the All Tasks-> Manage Private Keys.
• Click on Add and then type “IIS APPPOOL/[APPPool Name]”, click on Check Names, and then click on Ok. I have permitted reporting, reference data, marketing automation reporting, marketing automation, search, processing, collection, and content management.
