I am trying to export my CA certificate to move the CA to another server. I am getting the error "The private key is not exportable."

I've read a few things about if the cert was not created with Cert Server version 2.0 or later I will have this problem. First, I don't know when the cert was created. Second, I went throught this process when moving from Netware 6.5 to OES1 (I'm now going from OES1 to OES2), so is not being able to export the private key if before version 2.0 something new??

Otherwise, can someone suggest why I can't export the cert?

Thank you.
