I need to upgrade from Solr 4.4 to version 4.10.1 and am not sure if I need to reindex.
The following from http://wiki.apache.org/solr/Solr4.0 leads me to believe I don't: "The guarantee for this alpha release is that the index format will be the 4.0 index format, supported through the 5.x series of Lucene/Solr, unless there is a critical bug (e.g. that would cause index corruption) that would prevent this." I've been looking through the change logs and news and the following from http://lucene.apache.org/solr/solrnews.html makes me think that maybe I do need to reindex: "Solr 4.6 Release Highlights: ... New default index format: Lucene46Codec ..." It will not be an easy task to reindex the files so I am hoping the answer is that it is not necessary.
