Hello All,
I am planning to upgrade from Solr 1.4.1 to Solr 3.1. I
saw some deprecation warnings in the log as shown below
[#|2011-05-09T12:37:18.762-0400|WARNING|sun-appserver9.1|org.apache.solr.analysis.BaseTokenStreamFactory|_ThreadID=53;_ThreadName=httpSSLWorkerThread-9001-13

so I would love the experts advise on the following questions
1. Do we have to reindex all content again to use Solr 3.1 ?
2. If we don't reindex all content are there any potential issues ? (I
read somewhere that first commit would change the 1.4.1 format to 3.1.
have the analyzer's behavior changed which warrants reindexing ?)
3. Apart from deploying the new solr 3.1 war; Is it just enough to set
"<luceneMatchVersion>LUCENE_31</luceneMatchVersion>" to get all the
goodies and bug fixes of the LUCENE/SOLR 3.1 ?
Thank You,
