Storage API Populate provides a mechanism to move existing files into Storage API.

It works with both Storage API Stream Wrappers and Storage API's core_bridge submodule.

Per field or global migrations are possible (see screenshot). Global migration is only available when Storage API Stream Wrappers is in use. Per field migrations are available for fields after they have been configured to work with Storage API.
