# Validate One Migration Request

**POST /api/atlas/v2/groups/{groupId}/liveMigrations/validate**

Verifies whether the provided credentials, available disk space, MongoDB versions, and so on meet the requirements of the migration request. If the check passes, the migration can proceed. Your API Key must have the Organization Owner role to successfully call this resource. Deprecated versions: v2-{2023-01-01}

## Parameters

#### Path parameters
- **groupId** (string)
  Unique 24-hexadecimal digit string that identifies your project. Use the [/groups](#tag/Projects/operation/listProjects) endpoint to retrieve all projects to which the authenticated user has access.

**NOTE**: Groups and projects are synonymous terms. Your group id is the same as your project id. For existing groups, your group/project id remains the same. The resource and corresponding endpoints use the term groups.

#### Query parameters
- **envelope** (boolean)
  Flag that indicates whether Application wraps the response in an `envelope` JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.
- **pretty** (boolean)
  Flag that indicates whether the response body should be in the prettyprint format.

## Body parameters
Content-type: application/vnd.atlas.2024-05-30+json

- **destination** (object)
  Document that describes the destination of the migration.
- **dropDestinationData** (boolean)
  Flag that indicates whether the migration process drops all collections from the destination cluster before the migration starts.
- **migrationHosts** (array[string])
  List of migration hosts used for this migration.
- **sharding** (object)
  Document that configures sharding on the destination cluster when migrating from a replica set source to a sharded cluster destination on MongoDB 6.0 or higher. If you don't wish to shard any collections on the destination cluster, leave this empty.
- **source** (object)
  Document that describes the source of the migration.
