lightroom 4 - Organize messy collection of raw files

Over the years I used different cameras and have a huge messy picture collection.

To be sure not to loose any pictures I copied them several times on different external hard drives changing often the way and the tool I used to organize them.

Now I have a big 10tb raid drive that I think could contain all my orignal files I'd like to move all the raw pictures from all the external drives to it.

The organization folders would be

->year

--->month
------>day
------->all the original files (jpeg and raw) untouched 

I'd like a tool that:

• Could find all the original files (jpeg or raw) based on patterns of camera (ex IMG_*.RAW, DCIM)


• Move all the files to the new drive using the folder structure above (reading exif data)


• Ensure that before deleting the file on the original drive it was really copied successfully to the destination folder.


• Skipping copying but deleting on the original drive if i find an exact duplicates of the picture in the destination folder.

I have Lightroom but do not know if I can use it for this and I have yet to understand it's internal organization. I'd like also to be independent of the tool I will use to edit and tag my pictures.
