Backing up the OpenSearch 1.x data

Starting with BMC Helix IT Operations Management version 24.3, OpenSearch 2.15 is supported for improved security.

The upgrade from OpenSearch 1.x to 2.15 is an in-place upgrade and does not require additional steps. However, it is important to back up your OpenSearch data before the upgrade.

Before you begin

  • Make sure you run the Upgrade configuration utility .
  • For the upgrade to be successful, you must provision additional processors, memory, and storage.
     See sizing considerations for more information about the resources required for the migration.
  • You can reclaim the resources after the upgrade.


To back up OpenSearch data

  1. Go to helix-on-prem-deployment-manager/utilities/migration/opensearch

    To view the help options, run the following command: ./es-opensearch-migration.sh -h 

  2.  To back up OpenSearch 1.x data, run the following script:

    ./es-opensearch-migration.sh backup

    A temporary MinIO is created to save all the OpenSearch data.

    After the backup is complete, you will get the following messages:
    EventES Backup Job is successful.
    LogES Backup Job is successful.

  3. (Optional) To verify that a temporary MinIO was created, run the following command:

    kubectl -n <ITOM namespace> get pod | grep es-minio

    Sample output:
