For major upgrades, I'd suggest that this is the way to go.
When significant things change (such as redefinitions of major class 
hierarchies, or modularization of the image, etc), providing an 
automatic system which re-enacts this change in arbitrary images is 
almost impossible.
Sometimes it works (that's where the upgrade stream gets used), 
sometimes it won't.
Where it does not work, exporting code into fileouts or repositories 
normally works pretty well, and saving content as project files is not 
too bad either.
