I am running solrcloud version 4.3.0 with a 10 m1.xlarge nodes and using zk to manage the state/data for collections and configs.I want to upgrade to version 4.4.0.
When i deploy a 4.4 version of solrcloud in my test environment, none of the collections/configs (created using the 4.3 version of solr) that exist in zk show up in the core admin. I should also mention that, all of my collection configs for solrconfig.xml have <luceneMatchVersion>LUCENE_43</luceneMatchVersion>. Should i change the lucene version to match lucene_44 (match solr version?) to get it working again? What is the best way to upgrade to a newer version of solrcloud without deleting and recreating all configs and collections? Kindly advise -- Best -- C
