Subject Upgrade from solr 4.4 to 4.10.1
Date Thu, 02 Oct 2014 16:06:55 GMT
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 leads me to believe I
"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 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.

Thanks for any advice,
