Adjusting a boundary shapefile based on GPS data points

I have several shapefiles representing boundaries of properties.  The length of the sides of these polygons is accurate, taken from surveys.  However, their location is not always accurate.  When visiting these properties, I took accurate GPS information at some of the boundary corners.  What I'd like to do is be able to match up these GPS points with the corners of the boundary shapefiles and have GIS adjust the shapefile. 

My first thought was to use Georeferencing, but I'm not sure that works for shapefiles which already have spatial information.
I then tried to use the Spatial Adjustment toolbar, but I'm not sure it has the settings I need. It seems like I want to spatially transform the shapefile (as opposed to edge matching or rubber sheeting), but I only want to rotate and translate the image, without doing any differential scaling or skewing.

I'm sure I'm missing something here, but can't figure it out.  Any thoughts?

Thanks in advance.
