Hello,

I am referring this article, and trying to migrate RMS to ADRMS :

http://technet.microsoft.com/en-us/library/jj835767(v=ws.10).aspx

I am stuck at a point where not able to create ssl certificate with old and new url of cluster, (able to do that for fqdn name of old and new server )

I tried using offline CRC creation wizard and also gui option in iis 7, but does not let me click next if I use url's.

later I would be using Microsoft 2003 CA to get a certificate, an bind it to iis
