Opening Lucene's 4.3 index with Lucene 5.3

Hi While trying to open Lucene's 4.3 index with Lucene 5.3; I get the following error: java.nio.file.NoSuchFileException: 1441701798/_by.cfs at sun.nio.fs.UnixException.translateToIOException(UnixException.java:86) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.ja

codec header mismatch

Recently I am getting lots of index corruption exception. I am using lucene 4.3. org.apache.lucene.index.CorruptIndexException: codec header mismatch: actual header=592666996 vs expected header=1071082519 (resource: MMapIndexInput(path="/2015/06/06/1433548802/_qn0.si")) 2015-07-03_04:31:38.57975
