For users of MDD Free

The best way to switch from MDD Free to MDD Pro is to deactivate the free version, then activate the pro version and reindex the Media Library. 


Media Deduper Pro indexes/tracks a lot more data than free does so the reindexing will be important to deduplicating your Media Library. Once Pro is active and running, we encourage you to delete the free version of the plugin.
