Objective

This guide explains how to identify OmniOS datastores in your Hosted Private Cloud and migrate the virtual machines they contain to supported datastores using VMware Storage vMotion.

Requirements

  • Access to the OVHcloud Control Panel
  • Administrator access to your vSphere environment (via vScope)
  • Basic knowledge of VMware vSphere and Storage vMotion
  • Available supported datastores as migration targets

OVHcloud will provide the necessary freespare storage space as part of the migration process led by our teams.

Instructions

Step 1 - Identify OmniOS datastores

  1. Log in to the OVHcloud Control Panel.

  2. Click on Hosted Private Cloud and select your PCC service.

    Access Hosted Private Cloud

  3. Go to the Datacenters tab.

    Datacenters page

  4. On the datacenter page, open the Datastores tab.

    • Datastores with the prefix tete-xxxx are OmniOS datastores.
    • Datastores with the prefix cluster-xxxx are FreeBSD datastores.

    OmniOS datastores must be migrated to supported storage to ensure service continuity.

  5. Before starting a vMotion, make sure that you have a supported datastore available in your infrastructure.

    In some cases, OVHcloud may already have provided you with a supported datastore. Check your configuration before moving on to the next step.

Step 2 - Access vSphere through vScope

  1. From the PCC General information tab, scroll down to Management interfaces.

  2. Click on vScope.

    You are now connected to the vSphere interface and can perform a Storage vMotion.

Step 3 - Migrate a virtual machine with Storage vMotion

Performing a Storage vMotion may cause temporary performance disruptions.

For best results:

  • Reduce I/O activity during migration (stop intensive workloads if possible).
  • Plan the migration during off-peak or non-working hours.
  • Always ensure you have at least two supported datastores in your infrastructure for resiliency.
  1. In vSphere, right-click the virtual machine to migrate and select Migrate....

    Start migration

  2. Choose Change storage only.

    Select storage only

  3. Select a supported datastore as the destination.

    Select datastore

    You can also use the Advanced option to migrate only one disk if the VM has multiple disks.

    Advanced datastore selection

  4. Click Finish to start the migration.

    Finalize migration

  5. Monitor the migration progress in the Recent Tasks panel. Duration depends on VM size, IO activity, and available bandwidth.

    Migration progress

After migration, consolidate your workloads on supported datastores. Always keep at least two active datastores in your infrastructure to ensure service availability and redundancy.

Step 4 - Migrate VM templates

  1. In vSphere, go to VM template in folders to display the templates stored on your datastore.

  2. Right-click each template and select Remove from Inventory.

    Remove from Inventory

    The template is removed from the inventory but remains stored in the datastore. You can retrieve it and move it to another datastore, or delete it if no longer needed.

  3. Go to the Files tab, select the template folder, and click Move to.

    Move template files

  4. Choose the destination datastore and confirm with OK.

    Confirm datastore

  5. Once the files are moved, go to the new datastore, select the template file, and click Register VM.

    Register VM

  6. Follow the wizard: click NextNextFinish.

    Wizard step - Next

    Wizard step - Next

    Wizard step - Finish

  7. The template will appear in the VM & templates view.

Migration timeline

The migration schedule is as follows:

  • September 2025: Official communication sent to all customers.
  • October to November 2025: Period during which the customer can perform the migration autonomously.
  • November to December 2025: 40-day window for OVHcloud-led migration. A notification email is sent 3 to 4 days before the maintenance operation.
  • January 2026: Start of billing for the new datastore.
  • February 2026: Closure of the migration process.
