Documents with non-zero classNameId's (whether this is done through modification or when created) will not be migrated when migrating the document library. With the exception of images, MB attachments, and Wiki attachments, these documents are kept from being migrated by a constraint checked during migration.

Steps to reproduce:
1. Create a document under default file system store
2. Modify the classnameid and classPK in DLFileEntry table to a number other than 0, such as 11111
3. Perform data migration to AdvancedFileSystem store or to anything different from the current store
4. Restart server after updating portal-ext and attempt to download the file

Expected results:
File is available
Actual results:
File returns "resource not found"
