I am trying to migrate files from a 6.5 server to OES 11. I am getting the following error.

Error: File /opt/novell/migration/plugin/conf/SourceServerCert.der is not a valid certificate file. No 'BEGIN CERTIFICATE' string

That is the failure and then it won't let me contect to the source server. I have tried both secure and non secure ports. The weird thing is that it worked great for awhile. I moved a lot of data on several 6.5 server to OES servers and then it just stopped working. I have tried reboots on all servers involved and have tried several different 6.5 and OES servers with no luck.

Any help?
