Hi Team,
We planning to upgrade SOLR from 5.2.1 to 7.x version. I just googled and found that there is no way of upgrading from 5.x to 7.x directly Here are the list of suggestions gathered from different sources 1. We cannot upgrade directly from 5.x to 7.x instead upgrade to 5.5 then upgrade to 7 as there is major index format level changes taken place in 5.5 or later version. 1. Use index upgrade tool which can allow to upgrade all old indexes to new index format then we can upgrade to 7.x version easily. We are really struggling to get the right options here for this upgrade. I Know we are running very old version. We need this to be happen ASAP. Can you please suggest us what is the right approcuh here to upgrade from 5.2.1 version to 7.x version. Thanks, Padmanabhan -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
