Here's an example of its use: You have a site with News documents and 
PressRelease documents. At some point, you decide to merge the two types 
into just News. Updating the profile is easy, but you'll still have to scan 
you database documents and modify the portal_type of the former 
PressReleases, and maybe adjust some attributes. That's what upgrade steps 
are for in CPS.
