>            Reporter: David Johnson
>            Assignee: David Johnson
>            Priority: Critical
>             Fix For: 5.0

>   Original Estimate: 48h
>  Remaining Estimate: 48h

> Must be able to migrate old File Upload resources to new Media File Upload format for 5.0.
> Proposed solution:
> - Use new property names for the media-file storage and resource root URL. 
>    # The directory in which Roller will upload files
>    mediafiles.storage.dir=${user.home}/roller_data/mediafiles
>    # The context path under which resoures will be made available
>    mediafile.resource.url=/resources
>    # Migrate old file resoures to Roller 5.0 Mediafile Storage automatically
>    uploads.migrate.auto=true
> - On startup, if Roller finds that the 'uploads.dir' property is set and 
>   points to a valid directory, then Roller will check the directory for files 
>   and a migration-status file. If migration status is incomplete, then Roller 
>   will resume migration until complete.
>      * Implemented the "on startup" part in the JPAMediaFileManager.initialize()
> - Migrating a file means copying it from the old 'uploads.dir' to the new 
>   'mediafiles.storage.dir' directory, but doing so by using only native Java SE 
>   file APIs and the new MediaFile manager to do so (i.e. do not depend on the 
>   old FileManager interface, which will be removed).
>  
>   (do it via copy so that old URLs still work until FileManager is refactored
>   out of existance, see ROL-1816)
