DESCRIPTION¶

This class extends the Search::Elasticsearch client with a "migration" namespace, to support the API Migration APIs <https://www.elastic.co/guide/en/elasticsearch/reference/current/migration-api.html>.

"deprecations()"¶

    $response = $es->migration->deprecations(
        index => $index      # optional
    )

The "deprecations()" API is to be used to retrieve information about different cluster, node, and index level settings that use deprecated features that will be removed or changed in the next major version.

See the deprecations docs <https://www.elastic.co/guide/en/elasticsearch/reference/current/migration-api-deprecation.html> for more information.

Query string parameters:
"error_trace",
"human"

"get_assistance()"¶

    $response = $es->migration->get_assistance(
        index => $index | \@indices      # optional
    )

The "get_assistance()" API analyzes existing indices in the cluster and returns the information about indices that require some changes before the cluster can be upgraded to the next major version.

See the get_assistance docs <https://www.elastic.co/guide/en/elasticsearch/reference/current/migration-api-assistance.html> for more information.

Query string parameters:
"allow_no_indices",
"error_trace",
"expand_wildcards",
"human",
"ignore_unavailable"

"upgrade()"¶

    $response = $es->migration->upgrade(
        index => $index       # required
    )

The "upgrade()" API performs the upgrade of internal indices to make them compatible with the next major version.

See the upgrade() docs <https://www.elastic.co/guide/en/elasticsearch/reference/current/migration-api-upgrade.html> for more information.

Query string parameters:
"error_trace",
"human",
"wait_for_completion"
