Great!

I think it would be good to catch in .to22.check_dcmi_metadata *all* 
tools that don't have a 'DCMI' attribute.

CMF 2.0 and 2.1 did not add '_DCMI' in __init__, I just changed that 
before the 2.2 beta. If the old migration code was never triggered the 
tools are broken without an upgrade step.

Yes. All migration code is now linked to the default profile of 
CMFDefault. At the moment I have no idea how to make these upgrade steps 
available for people who use e.g. only CMFCore.
