Hello Erick, Thanks for your reply!
You mean that, we should follow below steps right? Here is the data directory path : solr/solr-8.2.0/server/solr/product/item_core/data STEPS :- 1. Stop old solr-8.2.0 server 2. Copy data directory (from old solr version to new solr version) copy solr/solr-8.2.1/server/solr/product/item_core/data to solr/solr-8.3.1/server/solr/product/item_core/data 3. Start new solr version solr-8.3.1 Is it correct way to copy just index only from old to new solr version? Is it lose any data or anything break in new solr version ? Thanks in advance! -Ken
