Replacing trusted CA certificates

When a trusted CA certificate has been updated by a trading partner, you can replace it in the certificate store while retaining the original file name so the partner’s certificate defined in your host configurations does not need to be updated.

1. In the web UI, go to Administration > Certificate Management > Certificates. In the native UI, go to Tools > Certificate Manager or click the Certificates button in the toolbar.
2. In the tree pane, right-click the intermediate CA certificate or root CA certificate that you wish to replace and select Replace > Trusted CA Certificate. 
3. Enter or Browse to the path of the new partner certificate that will be replacing the existing certificate and click Replace.
   Note: The extension of the new file must match the extension of the original file and the certificates must be of the same type. For example, you should not attempt to overwrite the contents of a .p7b file with the contents of a .cer file.
4. A dialog appears showing the content of the new and original certificates and asking for confirmation of the certificate replacement. By default, the original certificate file will be archived in the certs\archive directory and the archived file name will be appended with the current date/time stamp. If you do not want to archive the certificate, clear the Archive original file before replacing it with the new content check box.
5. Click OK.
