When you run the migration tool, the contents of the Cortex XSOAR database are read, and a corresponding object is created in Elasticsearch. The migration tool is run from the main database machine and from each database node. 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. All commands are run from the Cortex XSOAR server machine. To migrate your data, use the migration tool. You cannot run more than one migration tool process at a time. {% hint style="info" %} ### Note * 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](/xsoar-6-administrator-guide/6.14/onboard-cortex-xsoar/elasticsearch/migration/validate-the-migration-to-elasticsearch.md). {% endhint %} 1. For the main database, copy the Cortex XSOAR database either by taking a snapshot OR manually create a copy of the **`/var/lib/demisto/data`** directory and the `demisto.conf` file. Then follow the same procedure for each node. 2. Download the migration tool by appending **`downloadName=elasticsearch_migration_tool_6_x_x`** to the end of the download link that you received, when installing Cortex XSOAR. Replace **`X_X`** with the version number. 3. Copy your database and migrate data from the copy database to Elasticsearch. It is recommended to copy your data up to the last three months, without any downtime. If you do not want to do this, go to step 4. 1. Copy the Cortex XSOAR database by doing one of the following: * Take a snapshot of the database. * Manually create a copy of the **`/var/lib/demisto/data`** directory. 2. Copy the `demisto.conf` file. 3. Edit the copy of the `demisto.conf` file, by adding your [Elasticsearch configuration](/xsoar-6-administrator-guide/6.14/onboard-cortex-xsoar/elasticsearch/elasticsearch-setup/elasticsearch-configurations.md). Ensure that the same Elasticsearch object exists in the `demisto.conf` on the app server and the main database and hat **`elasticsearch`** is the top-level object in the **`demisto.config`** file (within the main curly brackets). Edit the copies of `demisto.conf` for the main database and for each node to add your [Elasticsearch configuration](/xsoar-6-administrator-guide/6.14/onboard-cortex-xsoar/elasticsearch/elasticsearch-setup/elasticsearch-configurations.md). 4. For the main database and for each node, using **`demisto`** or **`sudo`** permissions, run the following command: **` sudo ./elasticMigrator -config-path`` `` `*****``*****`-db-path`** `` -`` For a full list of the flags, see [Migration Tool Flags](#migration-tool-flags). For example, to exclude the last 3 partitions from the migration, 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`** When you run the migration tool, parameter values specified in the `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.config` file. 5. Complete steps 1 to 3 in [Validate the migration](/xsoar-6-administrator-guide/6.14/onboard-cortex-xsoar/elasticsearch/migration/validate-the-migration-to-elasticsearch.md). 4. After the migration of the data is complete and validated, migrate your remaining data from the active database to Elasticsearch. 1. Create a backup copy of the **`demisto.conf`** file for your active database. 2. Edit the original `demisto.conf` file (not a copy) for the main database and for each node to add your [Elasticsearch configuration](/xsoar-6-administrator-guide/6.14/onboard-cortex-xsoar/elasticsearch/elasticsearch-setup/elasticsearch-configurations.md). Ensure that the same Elasticsearch object exists in the `demisto.conf` on the app server and the main database. 3. For the main database and for each node, stop the Cortex XSOAR server. Ubuntu: **`sudo service demisto stop`** 4. For the main database and for each node, 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. 5.

Log individual failed items, either in a single meta file, or file per item failure. Values:

0: Does not log failed items (default).

1: Logs failed items metadata in a single file.

2: Logs each failed item in an individual file under the log folder. For more information, see Troubleshoot Elasticsearch.

| 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-to-ignore`** | String | Comma-separated list of partitions to exclude. | Optional | | **`partitions`** | String | Comma-separated list of partitions to migrate. If no partitions are specified, all partitions are migrated. | Optional | | **`previous-results`** | N/a | Show results of the previous migration. | Optional | | **`skip-existing-indicators`** | Boolean |

Existing indicators are not modified during the migration. Values:

true

false (default)

| Optional | | **`object-max-size`** | Integer | The maximum size, in megabytes, of objects that will be migrated to Elasticsearch. The default is 100 MB. | | | **`retry-large-objects`** | Boolean | Retry the migration of large objects when rerunning the migration tool. 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. | | | **`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. | | | **`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. | | | **`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. | | | **`version`** | N/a | Prints the migration tool version. | Optional | | **`y`** | N/a | Answers yes to all questions, unless there is an error. | Optional | --- # Agent Instructions This documentation is published with GitBook.
