I discovered some code in filestore2.module for converting files from filestore to filestore2. The code looks like it works, but it's hard to find how to run it. I was able to display the menu of conversion options with this url:

admin/settings/filestore/convert

But the display of conversion options generates incorrect links. The code is below. I believe that this works if each path is changed from "admin/system/modules/filestore2/convert" to "admin/settings/filestore/convert". I also had to install the 4.4 version of filestore.module.
