2007 -> 2013 Upgrade .webpart and .dwp's

I recently did an upgrade from 2007 to 2013.  The content database is in 2013 version and the site collection has been upgraded to 2013.

But what we are noticing is that even after I reactive 2013 Publishing on every site/web the webparts in the webpart gallery are still referrencing version 12 of the sharepoint dll's.

E.g. The content query webpart did not show up in content rollup.  It's in the Default group and it's type is referencing version 12.  So I deleted the .webpart for it and reactivated publishing and poof the COntent Query Webpart showed up where it's suppose to and it works now.

Then on a whim I made a tool download all of the .dwp and .webpart files from the webpart gallery and used a search tool to scan them for version 12 references.  I found this list:

My question is.... Is there a way I can upgrade these to 2013.  I know that some of these won't have 2013 versions, but I can see 3 right of the bat that do.  Is there a way to get the publishing feature to overwrite them?  Or someone bench these to a sub folder or something?

I'm looking for the right way to do this, I could just delete them all and reactivate everything and see what shows up, but then I might me missing .webpart/.dwp's that are still needed.
