I used it to migrate from t7 to t10 and recreate more easily my galleries.
Step 1 .... Convert the td4 to a tdb8 database.
Step 2 .... Use the Metadata Editor to push all the gallery names that the image is assigned to and the keywords into the Metadata of the image so that the gallery assignment ( name) and the keywords always travels with the image. ( See image attached) and push annotations to the metadata comments. the keywords and gallery names are pushed to the metadata keywords field
Step 3 .... In the keywords preferences set the thumbs db to grab gallery names that are in the in the metadata and put them in the Keywords in the t10 db.
Step 4 .... Manually create the gallery tree/folder names ( they will have no thumbnails yet)
Step 5 ... Do a keyword search on each gallery name ( because the gallery name has been key-worded) and then select all those images and slide them to the gallery. This creates the pointers and gets the images indexed to the right gallery.
Step 6 ... refer to the thread and Daans posts about it all..
