Upgrading from Elasticsearch to OpenSearch

This procedure describes how to upgrade from Elasticsearch and Kibana (deprecated in Control-M) to OpenSearch and OpenSearch Dashboards in Control-M Workflow Insights.

Before You Begin

  • Define a Workflow Insights backup, as described in Defining Workflow Insights Backups.

  • Copy the Workflow Insights cluster backup location that you defined in Configuring Workflow Insights, and paste it to the following location:

    UNIX/Linux: ~/BMCINSTALL/uninstall/DRNFT.<Current_Version>/Backup_Elasticsearch_Snapshots

    Windows: "%EM_HOME%\BMCINSTALL\uninstall\DRNFT.<Current_Version>\Backup_Elasticsearch_Snapshots"

  • Install Control-M/EM 9.0.21.200, as described in Control-M Upgrade.

  • Verify that the Control-M/EM Configuration Agent is Up.

  • (Control-M Full Install only) Verify that the Control-M/Server is Down.

Begin

  1. Log in as a Control-M/EM user.

  2. Run the following command to stop Elasticsearch and Kibana:

    In a Control-M/EM Cluster or High Availability Configuration, you must consecutively run this command on every host before you move to the next step.

    • UNIX/Linux:

      em bmcpython ~/ctm_em/services/bin/opensearch_update/opensearch_manager.py stop

    • Windows:

      bmcpython "%EM_HOME%\services\bin\opensearch_update\opensearch_manager.py" stop

  3. Run the following command to install OpenSearch and OpenSearch Dashboards:

    In a Control-M/EM Cluster or High Availability Configuration, you must consecutively run this command on every host.

    • UNIX/Linux:

      em bmcpython ~/ctm_em/services/bin/opensearch_update/opensearch_manager.py install

    • Windows:

      bmcpython "%EM_HOME%\services\bin\opensearch_update\opensearch_manager.py" install

  4. Run the following command to verify that OpenSearch service is running:

    em services-cli -st

Uninstalling OpenSearch

This procedure describes how to uninstall OpenSearch and OpenSearch Dashboards and restore Elasticsearch and Kibana in Control-M Workflow Insights. You must uninstall OpenSearch when you downgrade from 9.0.21.200 to Control-M/EM 9.0.21.100 and lower.

Begin

  1. Log in as a Control-M/EM user.

  2. Do the following:

    1. Run the following command to view the backups that can be restored:

      UNIX/Linux: em bmcpython <install path>/ctm_em/services/bin/elasticsearch_restore.py snapshots

      Windows: bmcpython "%EM_HOME%\services\bin\elasticsearch_restore.py" snapshots

      A list of backups appears.

    2. From the list of backups, find and record the backup Name that you want to restore.

  3. Uninstall Control-M Workflow Insights, as described below:

  4. Run the following command to downgrade Control-M/EM:

    • UNIX/Linux: ~/BMCINSTALL/uninstall/DRNFT.9.0.21.200/uninstall.sh

    • Windows: "%EM_HOME%\BMCINSTALL\uninstall\DRNFT.9.0.21.200\uninstall.exe"

  5. Reinstall Control-M Workflow Insights, as described below:

  6. Restore Elasticsearch with the backup Name that you recorded, as described in Restoring a Workflow Insights Backup.
