Subject Re: Solr upgrade to latest version
Date Wed, 24 Sep 2014 05:23:45 GMT
Hi,

Currently I am using SOLR 1.4.1 and want to migrate to SOLR 4.9.

Is there any manual or link for 1.4 to 4.9? Which can guide step by step on

1. solrconfig.xml changes

2. schema.xml changes

3. changes required in version 1.4.1 queries.


Thanks

Vivek
