Hi, I would like to upgrade from Solr 4.10.3 to Solr 5.2.1 and I have 6 cores all the same version 4.10.3. When I start 5.2.1, 5 cores are started correctly and 1 core (most important 130M docs) fails. I got the message: Error opening new searcher, because:
org.apache.lucene.index.CorruptIndexException: codec mismatch: actual codec=Lucene46SegmentInfo vs expected codec=Lucene50SegmentInfo Can I do something? Please help. :) -- View this message in context: http://lucene.472066.n3.nabble.com/codec-mismatch-tp4222276.html Sent from the Solr - User mailing list archive at Nabble.com.
