Migrating Plesk SSL between servers

[VinnyT]

Hi. I am in the process of migrating plesk servers. I have downloaded the CERT used to secure the old panel (via the download option in plesk). The download is a PEM file.

I try uploading that PEM file to the new plesk panel, but I get the following errror: Error: Unable to find the appropriate private key for the certificate.

I have also tried manually moving the PEM file to: /usr/local/psa/admin/conf/httpsd.pem and /usr/local/psa/etc/httpsd.pem, but that does not seem to work.

Any idea what is going wrong? The private key is in the file...
