You can migrate all vApps, independent disks, and catalog items of one or more organizations from one or more datastores to different datastores.

Before you decommission a datastore, you must migrate all the items stored on that datastore to a new datastore. You might also want to migrate an organization to a new datastore that has more storage capacity or uses a newer storage technology such as VMware vSAN.

Important:

Tenant storage migration is a resource-intensive operation that can run for a long time, especially when there are many assets to migrate. For more information about migrating tenant storage, see https://kb.vmware.com/kb/2151086.

Prerequisites

  • For each storage policy containing a source datastore that you want to migrate, verify that there is at least one destination datastore to which to migrate. You can create destination datastores or use existing ones. For further information about determining the datastores in the storage policies used by the target organizations, see the vSphere Storage documentation.
  • Create a VMware Cloud Director API session as a system administrator or with a role that has the Organization: Migrate Tenant Storage right.

Procedure

  1. Retrieve the XML representation of the vSphere platform extensions.
    Use a request like this one. 
    GET https://vcloud.example.com/api/admin/extension
  2. Examine the response to locate the Link element that contains the URL for migrating tenant storage. 
    <Link
   type="application/vnd.vmware.cloud.tenantMigrationParams+xml"/>"
   rel="add"
   href="https://vcloud.example.com/api/admin/extension/action/migrateTenant"/>
  3. Create a TenantMigrationParams element that includes the source and the target datastores and references one or more organizations to migrate.
  4. POST the TenantMigrationParams element you created in Step 3 to the URL described in Step 2.
    See the request portion of Migrate Tenant Storage.

Example: Migrate Tenant Storage

This example migrates items owned by organization with reference https://vcloud.example.com/api/org/26 from datastore https://vcloud.example.com/api/admin/extension/datastore/100 to datastore https://vcloud.example.com/api/admin/extension/datastore/200.
