transferring private key to from old web server to plesk server

[ferdz]

I have a problem with your Plesk application.

I am currently trying to migrate my companies Web server to another server (with plesk).

I have successfully exported the private key from the original server successfully. The file that was exported had an file extension like filename.pfx.

When trying to Import this into Plesk I have absolutely no luck. It gives me error message

Unable to set private key the private key format is invalid

The following is what im doing:

* Click server Click Certificates Click Add
* Enter Certificate name (Fill in form)
* Attach private key file via the browse button
* Attach the certificate via the browse button


I would be very grateful if you could give me some assistance.
