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 ?
If you think that you've got index files from 1.4 still hanging around,
you should optimize the indexes in 3.5 before upgrading further, to
convert the index. The new version will NOT read index segments that old.
