I believe I have covered all of the steps in the guide, however after migrating my enterprise root CA from 2008 to 2012, the Delta CRL Location #1 and #2 appear to be pointed to the old CA. While DeltaCRL Location #1 is working (ldap://), the CN is the name of the old CA. The DeltaCRL Location #2 is pointing to http://oldca which of course is incorrect.
As a quick side note, I published a new CRL / Delta CRL and this fixed some of the issues (DeltaCRL Location #1 has the correct CN now), however it removed DeltaCRL Location #2 (Http://) completely. I verified the extension is configured to include the http:// path, so I'm not sure why it's missing.
