Migrating from from other media library folder plugins

Hi pre-sales team:

We currently use Media Library Folders Pro to manage a very large number of files which are offloaded to S3, and use a custom URL. Before considering changing plugins, we need to assess the impact in time and workload of our developers, and impact to our customers, Is there a simple migration process for physical folders from MLFP to WP Media Folder or a recommended process from which we can determine an impact? Additionally, is there any sort of "free for development" version of the plugin (something that limits number of files possibly) so we can test the process to see if it's feasible?

Thanks in advance, Steven.
