Hi, we are planning for a Solr Cloud upgrade from 4.7.1 to 4.10. I have identified the following steps for the upgrade
1. Update solrconfig.xml to be compliant with 4.10. 2. Update the required jar files and war files from Solr 4.10 distribution. 3. Verified we are using Java 1.7. Now comes the question of data - index, do I need to recreate the indexes from scratch, basically trunk and load or is there some other way to upgrade the indexes? Any guidance you can provide will be very helpful. Nitin
