Thanks Tomas/Shawn! One more question related to backward compatibilty. Previously we had upgraded our solr master/slaves from 1.4 version to 3.5 version - We didn't reformat the whole index then. So i believe there will be some files with 1.4 format present in our index.
Now when we upgrade from 3.5 to 4.1/or4.2 - Can we expect solr slave version 4.x to read both 1.4 and 3.5 formatted indices, without any issues ?
