Hopefully, you have an SRDF license. Snap your DB luns and mount them onto the PPC box. If all goes well, there is your way. You will have to put the database into the backup mode ("ALTER DATABASE BEGIN/END BACKUP") and recover it to the point in time. Make sure that the snap is mounted to the same mount point as on the original machine.
