[jira] Created: (LUCENE-2441) Create 3.x -> 4.0 index migration tool

Create 3.x -> 4.0 index migration tool
--------------------------------------

                 Key: LUCENE-2441
                 URL: https://issues.apache.org/jira/browse/LUCENE-2441
             Project: Lucene - Java
          Issue Type: New Feature
          Components: Index
            Reporter: Michael McCandless
             Fix For: 4.0.0


We need a tool to upgrade an index so that 4.0 can read it.  I think the only change right now is the cutover to flex's standard codec format, but with LUCENE-2426 we also need to correct the term sort order to be true unicode code point order.
