Dear all,
Our project is still running on Lucene Core 3.2.0, which is a little too
old. If we wanna upgrade the version from 3.2.0 to 6.1.0, is there any
compatibility issue, which requires some special actions?
Appreciated for your advice
Regards, Wenxing
Yes. Lucene only guarantees back-compatibility with
indexes for one major version. That is, a 4.x release can
read a 3.x Lucene index. But a 5.x will not read a 3.x.

2> upgrade in stages, check out the
For some of the segments we received the following exception during merge
as well as search. They look to be corrupt [Lucene 4.6.1 & Sun JDK
1.7.0_55]
Is this a known bug? Any help is much appreciated
The offending line of code is in ForUtil.readBlock() method...
*final int encodedSize = encode
