Reindex data

There are some situations where data coming in to Splunk SOAR can't be indexed and, as a result, can't be searched. In such cases, you can reindex information sections to make this information searchable.

If you are using Splunk SOAR version 6.2.0 or later, reindexing will send all your SOAR data to your Splunk Enterprise or Splunk Cloud Platform deployment again, which can result in duplicated data. To prevent duplicates, make sure to delete existing objects from all forwarder groups before reindexing. See How indexing works in the Splunk Enterprise Managing Indexers and Clusters of Indexers manual.

Here are some situations that require you to reindex your data:

• The embedded Splunk Enterprise or external Splunk Enterprise or Splunk Cloud Platform deployment was offline or unreachable.
• Upgrading Splunk Phantom from a version earlier than 4.0.
• Converting from a single Splunk SOAR instance to a cluster.
• Changing your search setting configuration, such as switching from using the embedded Splunk Enterprise to an external Splunk Enterprise or Splunk Cloud Platform instance.

Each option in the Section to Reindex drop-down list represents multiple database tables or information stores. For example, the Action index contains results for both action runs and app runs. The Playbook index covers both playbooks and custom lists.

To reindex your data, perform the following tasks in Splunk SOAR:

1. From the main menu, select Administration.
2. Select Administration Settings.
3. Select Search Settings.
4. In the Reindex Search Data section, select an information section from the Section to Reindex drop-down list.
5. Select Reindex.

Reindexing is resource intensive and can impact system performance. Large data sets may take some time to reindex.
