Abstract

Migrate Cortex XSOAR objects to Elasticsearch for a multi-tenant environment.

The migration tool migrates Cortex XSOAR objects to an Elasticsearch database. When you run the migration, the contents of the Cortex XSOAR database are read and a corresponding object is created in Elasticsearch.

You run the migration tool from the main machine and each host machine. Migrate the main account on the main host, then the tenants on the main host, and then proceed to the other hosts and tenant accounts. For complex environments with multiple host machines, we recommend migrating all tenants on the host before proceeding to the next host.

In the BoltDB, data related to incidents and indicators is stored in partitions by month. To minimize downtime during the migration, we recommend you create a copy of the database, then migrate data that is older than three months from the copy, while continuing to work in your current environment. Once the initial migration is completed, you should then migrate the last three months.

Note

If you are working in an environment with remote repositories, you must run the migration separately on each environment. For example, if both your development and production environments are going to be used with an Elasticsearch database, you must migrate each of those environments, and each environment must use a different index prefix.

When you run the migration tool, parameter values identified in the etc/demisto.conf file override values supplied for tool flags and default values. If no value exists in the demisto.conf file, values supplied in the tool flags override default values, but do not write the values to the demisto.conf file. For example, if the db-path is identified in the configuration file, the tool will use the value in that file, not the value supplied or the default value, when running the tool.

Note

  • You cannot run more than one migration tool process at a time.

  • Always migrate older data before newer data. Migrating partitions out of order can cause duplicate incident ids.

  • By default, the migration tool skips over objects larger than 100 megabytes. After the migration process runs, you can view the skipped large objects and determine whether to migrate them. For more information, see Validate the Migration to Elasticsearch.

  1. Download the migration tool by appending downloadName=elasticsearch_migration_tool_6_10_0 to the end of the download link that you received, when installing Cortex XSOAR.

  2. For each host you want to migrate copy your database and migrate data from the copy database to Elasticsearch.

    1. Copy the Cortex XSOAR database by doing one of the following:

    2. Copy the demisto.conf file.

    3. Edit the copy of the demisto.conf file, by adding your Elasticsearch configuration.

      Ensure that elasticsearch is the top-level object in the demisto.config file (within the main curly brackets).

    4. From the host, using the demisto or sudo permissions, run the following command: command with either demisto or sudo permissions. Specify the following:

      sudo ./elasticMigrator -config-path <path-of-copy-of-demisto.conf> -db-path <path-of-the-copy-of-the-demisto-data> -<flags>

      For a full list of flags, see Migration Tool Flags.

      For example, to exclude the last three months partitions, add the -only-old-partitions and -partitions-back flags: sudo ./elasticMigrator -config-path /usr/local/dev/copy_of_demisto.conf -db-path /usr/local/dev/lib_demisto_copy/data -only-old-partitions -partitions-back 3

      By default, the migration migrates the entire contents of the database and the tenants on the host.

      • To migrate only the host, use the skip-accounts flag.

      • To migrate all accounts, use the skip-main flag.

      • To migrate specific accounts, use the accounts and skip-main flags.

    5. Complete steps 1 to 3 in Validate the migration

  3. After the migration of the data is complete and validated, migrate your data from the active database to Elasticsearch.

    1. Create a backup copy of the demisto.conf file for your active database.

    2. Edit the demisto.conf for your active database to add your Elasticsearch configuration.

    3. On the host (main or any other) stop the Cortex XSOAR server by running one of the following commands:

      • CentOS: sudo systemctl stop demisto

      • Ubuntu: sudo service demisto stop

    4. From the host, migrate the remaining months from the active database to Elasticsearch. Run the sudo ./elasticMigrator command with either demisto or sudo permissions. Use the -partitions-back flag to specify the remaining partitions.

      For example, sudo ./elasticMigrator -partitions-back 3 migrates the last three partitions, which would include the current month and the previous two months, as well as the main partition.

      By default, the migration migrates the entire contents of the database and the tenants on the host.

      • To migrate only the host, use the skip-accounts flag.

      • To migrate all accounts, use the skip-main flag.

      • To migrate specific accounts, use the accounts and skip-main flags.

    5. Validate the migration (all steps).

      For any additional hosts that you want to migrate, repeat the steps above.

Migration Tool Flags

Optional

migrate-all

Boolean

By default, the Elasticsearch tool checks existing indices and migrates only the ones that are new. Using this flag, the Elasticsearch tool migrates all indices even if they currently exist. This is useful, for example, if there was an error or invalid data that was fixed. When used, the objects-to-migrate and objects-to-ignore flags are ignored. Values:

true (default)

false

Optional

objects-to-ignore

String

Comma-separated list of objects not to migrate. When the migrate-all flag is used, this flag is ignored.

Optional

objects-to-migrate

String

Comma-separated list of objects to migrate. When the migrate-all flag is used, this flag is ignored.

Optional

partitions

String

Comma-separated list of partitions to migrate. If no partitions are specified, all partitions are migrated.

Optional

partitions-to-ignore

String

Comma-separated list of partitions to exclude.

Optional

previous-results

N/a

Show results of the previous migration.

Optional

skip-accounts

With this flag, the entire bucket that contains the skipped large object is migrated again, which may include data that was previously migrated. If new data has been added in Elasticsearch since the earlier migration, this data will be overwritten.

Optional

force-main

Boolean

When the partitions flag is used, the -force-main flag forces the migration of the main partition as well as the specific list of partitions.

Optional

partitions-back

Integer

Provides an option to migrate X number of partitions back. For example, migrating three partitions back migrates the current month and the previous two months. If set to 0 or not used, all partitions are migrated.

Optional

only-old-partitions

Boolean

Can only be used with the partitions-back flag. Migrates all partitions other than the most recent partitions specified with partitions-back. For example, -partitions-back 3 -only-old-partitions migrates all partitions besides the current month and the two previous months. Should be used within the same calendar month as the previous migration.

strict-mode
