Migrating to vVols can be achieved easily by implementing the steps outlined in this chapter.
The migration process can be achieved by using the following procedure:
It is recommended to synchronize the time for all the hosts and vCenter Server instances.
Perform the following steps for all the hosts that will use vVols.
1. Select the host in the vSphere inventory.
2. Click the configure tab.
3. In the System section, select Time Configuration.
4. Click Add service or Edit and set up the NTP server.
Figure 20. vSphere Time Configuration
5. Select Use Network Time Protocol (Enable NTP client).
6. Enter the IP addresses of the NTP servers to synchronize with.
Figure 21. Time Configuration: NTP Servers Setting
7. Click OK. The host synchronizes with the NTP server.
8. Stop/Start as required.
To use vVols, The VASA provider must be registered with the vCenter. The storage capabilities are exported and presented to VMware based virtual infrastructure by using the protocol end points enabled by VASA.
Figure 22. VASA Storage Provider Registration
1. Login to vSphere client.
2. Go to vCenter Server in the vSphere Web Client navigator.
3. Click the Configure tab and click Storage Providers.
4. Click the + Add icon to register a storage provider.
5. Enter the connection details for the new storage provider, including the name, URL, and credentials.
6. Click OK to complete the registration.
Figure 23. VASA Storage Provider Registration
7. The storage provider VASA has been successfully registered with the vCenter as shown in Figure 22.
8. Once the VASA is registered, create a vVol based datastore to utilize vVol based services
1. Login to the vSphere Web Client.
2. Select the host in the vSphere inventory.
3. Right-click on the host and select the storage menu.
4. Click New Datastore.
5. Enter a unique datastore name.
Figure 24. vVol Virtual Datastore Creation
6. Select vVol as the virtual datastore type.
Figure 25. vVol Virtual Datastore Creation
7. Select the appropriate backing storage container which refers to the VASA that has been previously registered. This backing container will be used to host the virtual volumes.
Figure 25. vVol Virtual Datastore Creation
8. Click next to review the selections and click Finish.

9. At the end of the procedure, the newly created datastore can be viewed on the host.
10. To access the datastore on additional host(s), the datastore must be explicitly mounted on the required hosts based on the need.
1. Perform this procedure from the Storage view of the vSphere Client.
2. From the vSphere Client, go to the Storage view tab.
3. Right-click on the preferred vVol virtual datastore and click Mount Datastore to Additional Hosts
4. Select the available hosts to mount the Virtual Datastore and click OK.
Figure 27. vVol Virtual Datastore Host Connectivity
1. Select the required virtual machine in the vSphere inventory and click Migrate.
2. Select Change storage only and click Next.
Figure 28. Storage Migration: VMFS to vVol
3. Select the vVol datastore destination storage, virtual disk format (thick provisioning), and click Next.

4. Review the migration details including migration type, virtual datastore target, and disk format settings. Click Finish.
Figure 30. Storage Migration: VMFS to vVol
5. Depending on the number and size of the source virtual disks, it can take several minutes to complete the migration from VMFS to vVols.
6. You can check the status of the migration under the recent tasks tab of the vSphere client.

7. This migration process will create the necessary virtual volumes in the storage container of the storage system, as shown in Figure 32.
Figure 32. Storage Migration: Virtual Volumes
8. Upon the completion of migration, we can confirm the availability and mapping of the new vVol datastore by browsing to the datastores tab of the vm.
