====== Solr Upgrade in Place  ======



  - Under 'archive' project, modify the solr version in the build.gradle file then rebuild the solrdist.
  - Copy the solrdist to the target machine, and follow the instructions [[https://wiki.illinois.edu/wiki/display/clinecenter/Voyager+Processing+Engine|here]] to deploy the new solr instance.
  - Remember to remove the core you don't need. 
    - This solrdist creates 3 cores for you – gis, index, and shingles. 
    - Go to /usr/local/solr/server/solr and remove the cores that you are not using.
  - Check the solrconfig.xml that the core is pointing to the correct data directory.
  - Restart solr
    - Command: sudo systemctl restart solr
