I have and it works. I did this during the beta program. You just need all the 
proper pieces performed in the proper order.

Subject: Has anyone tried a server upgrade from 5.5.2.1 to 6.1.0.0?

Will a server upgrade from 5.5.2.1 to 6.1.0.0 work? Just wondering because
the server-upgrade directory on the storage ftp site is at 5.5.2.0 and
there is no server-upgrade directory under the patches directory for
5.5.2.1. The server upgrade book states that the upgrade utility must be at
the same level as the server.
