   • If you are using Cassandra 2.x:
     1. Copy the cf-schema-8.5.201.68.cql and cf-schema-8.5.201.79.cql files from /installation_path/gws/data/updates to the Cassandra node host.
     2. Run the following commands:

        cqlsh cassandra_host --file cf-schema-8.5.201.68.cql
        cqlsh cassandra_host --file cf-schema-8.5.201.79.cql

   • If you are using Cassandra 1.2:
     1. Copy the cf-schema-8.5.201.68.txt and cf-schema-8.5.201.79.txt files from /installation_path/gws/data/updates to the Cassandra node host.
     2. Run the following commands:

        cassandra_install_dir/bin/cassandra-cli -h cassandra_host --file cf-schema-8.5.201.68.txt

     /installation_path/gws/tools/rebuild-es-index.sh

   • If you use standalone Elasticsearch:
     1. Copy files from the /installation_path/gws/elasticsearch/templates folder to the templates folder on each Elasticsearch node.
     2. Run the following script on one Web Services and Applications node:

        /installation_path/gws/tools/rebuild-es-index.sh
