Migrate standalone root CA to enterprise root CA

Question

Hi all,
I've to migrate an existing standalone root ca, that runs on a Windows 2003R2 server to an enterpise root ca running on a windows 202r2 server.
is it possible in one hop?
I've found documentation about migrating from standalone 2003 to standalone 2012 
I've found no documentation about changing from standolne 2003 to enterprise 2012 or a 2 hop method (first 2003->2012 then stand alone -> enterprise)

As far as I know there don’t have document indicate we can “double hop” migrate 2003 standalone CA to 2012R2 CA, all document I can found indicate we can migrate the same type
CA to 2012r2.
