Hi, Sorry, I just noticed that you are using DirectDocValues format, which was experimental. You cannot directly upgrade this to 5.0. I would suggest to convert your index to use the default codec in 4.10 (e.g., by using addIndexes to a new index directory, or by forceMerge with an IndexWriter that has default codec).
After that you can read the 4.10 index with 5.0 using lucene-backward-codecs.jar in classpath.
