Re: Schema Change for Solr 7.4

Hi Shawn, thanks for this response. We are probably going to take your suggested approach: 1. Upload a new configset to ZooKeeper. 2. Create a new collection using the new configset. 3. Index data into the new collection. 4. Set up an alias with the original collection name, pointing at the ne
