Change Detection

[WilliamJones]

I have two polygon shapefiles that I would like to do a chage detection.  What is the process to achieve  this task in ArcMap 10.  Do i have to convert to a raster file?

Thanks for your help.

I would like to know in what ways the polygons are different; it is probably hard to describe. Would you be able to share sample data sets? you can email me: dlee@esri.com, if you prefer.
