A system administrator can migrate all of a tenant organization's vApps, independent disks, and catalog items to another datastore.

About this task

Before you decommission a datastore that backs a storage profile used by an organization VDC, you must migrate all the items stored on that datastore to new storage. Even if you're not decommissioning a datastore, you might need to migrate an organization to new storage to take advantage of additional storage capacity or newer storage  technologies  such as VMware vSAN. The vCloud Director storage migration wizard allows you to select one or more organisations and migrate their stored items from a source datastore to a destination datastore. Before you can migrate organization storage, you'll need to know which datastores the organization is using, and you'll need to create one or more datastores to serve as the destination.

Important:

Tenant storage migration is a resource-intensive operation that can run for a long time, especially when the organization owns many assets. See VMware Knowledge Base article https://kb.vmware.com/kb/2151086 for information that can help you plan and execute an effective storage migration.

Prerequisites

  • This operation is restricted to system administrators and custom roles that have been granted the Organization: Migrate Tenant Storage right.

  • The source and target datastores must be accessible to all vCenter Servers in the system.

  • Because migrating a vApp or catalog item must not change its storage profile, one or more of the destination datastores must be associated with each storage profile that's available in the organization VDCs backed by the source datastores.

Procedure

  1. Launch the wizard.

    There are two ways to launch the wizard, which follows the same workflow regardless of how you launch it.

    • Click the Manage & Monitor tab and click Organizations in the left pane. Right-click an organization name and select Migrate Tenant Storage.

    • Click the Manage & Monitor tab and click Datastores & Datastore Clusters in the left pane. Right-click a datastore or cluster name and select Migrate Tenant Storage.

  2. Select one or more organizations to migrate and click Add.

    Click Next to save your choices and continue.

  3. Select one or more source datastores and click Add.

    The wizard lists all datastores in the system. You can discover which of these datastores an organization is using by going to each of the organization's VDCs and listing the storage profiles they offer. Open each storage profile in the vSphere Web Client to see the datastores that are part of the storage profile. Select those datastores and click Add to add them to the set of source datastores for this migration.

    Click Next to save your choices and continue.

  4. Select one or more destination datastores and click Add.

    You can create destination datastores or use existing ones. At least one destination datastore must be associated with each storage profile that's available in the organization VDCs backed by the source datastores.

    Click Next to save your choices and continue.

  5. Review your selections and click Finish to begin the migration.

    You can use the Tenant Migration tab on the Logs page to monitor and cancel tenant storage migrations. See View Ongoing and Completed Tenant Storage Migrations.
