Migrate/Upgrade frommLucene 2.3
Dear all,
We are moving our codebase from Lucene 2.3 to 4.1. Also, we are
migrating the older indices from 2.3 to 3.6 and then to 4.1. Would be glad
if you can share some do's and dont's during migrating the indices, which
you have experienced before.
Also, the 2.3 indices were written using a standard analyzer then
and the current indices will use standard analyzer, version_41. Hope there
shouldn't be a problem reading the migrated indices because of the analyzer
version change? Thanks in advance. Glad if you can help.

Uwe, Just re-iterating so that I am understanding your statement right
without ambiguity. I use standard analyzer for all english and numerals. I
don't have a problem when reading 2.3 migrated indices with 4.1, right?
Sorry, for the doubt again.

In that case, it should be fine. Otherwise you would need to reindex.

Version.LUCENE_41 wouldn't affect right? Because I don't think I can use
Version.LUCENE_23 from the 4.1 code base.
Also, I am remembering something now. We had used CJK analyzer in the 2.3
version, for the japanese and chinese version. How about using the same in
4.1. Thanks in advance.

If you use StandardAnalyzer, you are in trouble unless you use StandardAnalyzer with Version.LUCENE_23 and you are using non-western language. If you change your code to use Version.LUCENE_41, you have to reindex.
