Hi, Yes, you may do this as a WAR upgrade. You may easily test this on a test copy of your index, and it should work just fine. Be aware though that once you have upgraded, you cannot go back. From Solr3.4.0's CHANGES.TXT:
* The Lucene index format has changed and as a result, once you upgrade, previous versions of Solr will no longer be able to read your indices. In a master/slave configuration, all searchers/slaves should be upgraded before the master. If the master were to be updated first, the older searchers would not be able to read the new index format. -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com Solr Training - www.solrtraining.com On 4. feb. 2012, at 20:11, Torlaf15 wrote: > Hallo, > > I hope somebody can help me. > > My Question: > Is it possible to copy the directory /solr/data/index from indexed from > Solrversion 3.2.0 to Solr 3.4.0. > > I want to use the new Solr-Version and want to put the Index from the old > one to the new Solr 3.4.0 > > Please forgive my bad english > > Greeds > Toralf > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/Copy-Index-from-Solr-3-2-0-to-Solr-3-4-0-tp3716021p3716021.html > Sent from the Solr - User mailing list archive at Nabble.com.
