Upgrade IT Service Intelligence in a search head cluster environment

After you deploy the new ITSI version to cluster members, you must also upgrade your indexers and ITSI license components.

If upgrading to the Python 3 release of Splunk (version 8.0), you must upgrade IT Service Intelligence and all other apps before upgrading Splunk Enterprise. For more information, see Python 3 migration with ITSI.

Before upgrading

Before you upgrade ITSI, you must perform all prerequisite steps specified in Before you upgrade IT Service Intelligence.

Step 1. Deploy the new version to the cluster members

Use the deployer to distribute the new version of ITSI to search head cluster members, the same way you initially deployed ITSI on the search head cluster. A migration script runs on the captain after upgrading. The upgrade then propagates to all other cluster members.

  1. Log in to splunk.com with your Splunk.com ID.
  2. Download the latest Splunk IT Service Intelligence product. The ITSI installation package includes the vmware_ta_itsi parent directory which contains components you need to deploy VMware data collection for SAI. If you don't want to deploy VMware data collection, remove the directory from the ITSI package before you upgrade your search head cluster. If you want to install the components in the vmware_ta_itsi parent directory, see Install VMware data collection add-ons and dependencies in the Install and Upgrade Splunk App for Infrastructure guide.
  3. Untar the ITSI installation package into $SPLUNK_HOME/etc/shcluster/apps/. For example:
    tar -xvf splunk-it-service-intelligence_<latest_version>.spl -C $SPLUNK_HOME/etc/shcluster/apps/
    

    On Windows, rename the file extension from .spl to .tgz first and use a third-party utility like 7-Zip to perform the extraction.

  4. Run the splunk apply shcluster-bundle command on the deployer:
    splunk apply shcluster-bundle -target <URI>:<management_port> -auth <username>:<password>
    
  5. Restart Splunk software. For example:
    cd $SPLUNK_HOME/bin
    ./splunk restart
    

When you restart Splunk Enterprise after installing the new files, a migration script runs to migrate existing ITSI knowledge objects to the new version. To check migration related logs, run the following Splunk search:

index="_internal" source= "*itsi_upgrade.log*"

For more information, see Use the deployer to distribute apps and configuration updates.

Step 2. Upgrade indexers

For non-clustered distributed environments, copy the SA-IndexCreation file to $SPLUNK_HOME/etc/apps on each indexer in your deployment. If you want to collect VMware vCenter Server data with SAI, install the components in the vmware_ta_itsi parent directory. For more information about what to install on the indexers, see Install VMware data collection add-ons and dependencies in the Install and Upgrade Splunk App for Infrastructure guide.

If you have an indexer cluster, use the configuration bundle method to replicate SA-IndexCreation across all peer nodes. On the master node, place a copy of SA-IndexCreation in $SPLUNK_HOME/etc/master-apps/. For information about updating peers in an indexer cluster, and for CLI instructions, see Manage app deployment across all peers in the Splunk Enterprise Managing Indexers and Clusters of Indexers manual.

Step 3. Upgrade ITSI license components

When you upgrade Splunk IT Service Intelligence, you must also upgrade SA-ITSI-Licensechecker and SA-UserAccess on any license master in a distributed or search head cluster environment.

If one of the search heads in your environment is also a license master, the license master components are upgraded when you upgrade ITSI on the search heads.
