Copy Index from Solr 3.2.0 to Solr 3.4.0

[Torlaf15 <fe...@hotmail.de>]

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

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.
