Greetings, We are planning to migrate from Solr 1.4 to Solr 3.5 (or, even new Solr version than 3.5, when available) in coming days. There are few questions about this migration.
• I heard, index format is changed in this migration. So, does this require me to reindex millions of data? • Are there any migration tool (or any other means?) available that would convert old indexes (1.4) to new format (3.5)? • Consider this case. http://myserver:8080/solr/mainindex/select/?q=solr&start=0&rows=10&shards=myserver:8080/solr/index1,myserver:8080/solr/mainindex,remoteserver:8080/solr/remotedata. In this example, consider that 'myserver' has been upgraded with Solr 3.5, but 'remoteserver' is still using Solr 1.4. The question is, would data from remoteserver's Solr instance come/parsed fine or, would it cause issues? If it results into issues, then of what type? how to resolve them? Please suggest. • We are using various features of Solr like, searching, faceting, spellcheck and highlighting. Will migrating from 1.4 to 3.5 cause any break in functionality? is there anything changed in response XML format of here mentioned features? Thanks in advance, Bhavnik **
