Hi all,
I have some indices indexed with lucene 5.5.0. I have updated my
dependencies and code to Lucene 7 (but my final goal is to use Lucene 9)
and when trying to work with them I am having the exception:
org.apache.lucene.index.IndexFormatTooOldException: Format version is not
supported (resource
BufferedChecksumIndexInput(MMapIndexInput(path=".......\tests\segments_b"))):
this index is too old (version: 5.5.0). This version of Lucene only
supports indexes created with release 6.0 and later.
I want to migrate from Lucene 5.x to Lucene 9.x. Which is the best
strategy? Is there any tool to migrate the indices? Is it mandatory to
reindex? In this case, how can I deal with this when I do not have the
sources of documents that generated my current indices (I mean, I just have
the indices themselves)?
Thanks,
