LR Finding relocated folders

Okay--so this is a fairly annoying issue that I'm having that resulted from my shifting (some time ago) from a structure like this:

---------------
Photos\2007-01-01\
.
.
Photos\2007-12-25\
Photos\2008-01-01\
etc.
---------------

to a structure like this:

---------------
Photos\2007\2007-01-01\...
Photos\2008\...
Photos\2009\...
etc.


Is there any easy way to find the 'missing files' in one fell swoop as opposed to going through every single folder ?

First off, use Lightroom to move and/or rename folders and it won't lose track!

Second off, if you do move them outside of Lightroom, pick a "high-level" folder that has been moved and in the Folders panel, right-click on it and select to "Find"...navigate to a matching folder and select it. Lightroom is pretty "smart" about this operation, but just be aware that the more "messing" with things you do outside of LR, the more "messing" you will have to do later!
