Since recently I was using v3.8 of XMM. I switched to v5.2 and imported my database from the older version. I followed by adding around 40 new movies in the database and I noticed that now I have some (a lot) duplicateactors.
How do I get rid of those duplicates without actually breaking the link with the movies those actors belong to? They have apparently different ActorIDs and new movie entries point to newly added actors although already present in the database. How can I deal with that? Is there a way to stop this from happening? Is there an easy way to remove duplicates safely without affecting linkage.
