Moving a Certificate from Apache to a Windows IIS Server.

1.) Back up your certificate:

To import your certificate to Windows, you will first need to combine your primary certificate, Intermediate (CA) Certificate, and your private key file into a .pfx type backup file. To do this, use the following command:

openssl pkcs12 -export -out DigiCertBackup.pfx -inkey your_private_key_file.txt -in your_domain_name.crt -certfile DigiCertCA.crt

This creates a backup of your primary certificate called DigiCertBackup.pfx. Copy this file to your IIS Server.

2.) Import the .pfx file to your Windows server
Once you have copied the .pfx file to your Windows server, follow the instructions for importing your .pfx file to Windows IIS server
