Migrate a cloud server disk

Last update: May 28 2025

Migrate a cloud server disk

Only the network drive can be migrated:

• to another segment of the pool any availability zone and any region — you can choose another project or account when migrating;
• to another project or account — only within one segment of the pool.

Move the disk to another segment of the pool⁠

To move a disk to another pool segment, you must create an image of the disk, move the image, and create a new disk from the image. You cannot directly move a disk to another pool segment.

When transferring a disk image, you can select a different project or account.

1. Create a disk image.
2. Transfer the image to another segment of the pool.
3. Create a disk from the image.

Move the disk to another project or account⁠

You can move a network disk to another project or account only within the same pool segment. You can migrate a single disk or several disks at once.

3. Go to the Disks section.
4. From the menu of the disk, select Transfer to another project.
5. Click Start Transfer. The disk will enter the AWAITING-TRANSFER status and will be unavailable for operation. The window that opens will display the data to complete the transfer — Transfer ID and Key.
6. Optionally, to cancel the migration at any time (putting the disk back into ACTIVE status), from the menu of the disk, select Manage migration and click Cancel migration.
7. In the adjacent browser tab, open the project to which you want to move the disk.
8. Go to Cloud Platform → Disks. Make sure that you open the list of disks in the same pool segment from which the disk is being migrated.
9. In the menu of the section header, select Accept disks from another project.
10. In the window that opens, enter the Transfer ID and Key that you received in step 5. Click Accept.

6. Optionally, to cancel the migration at any time (putting the disk back into ACTIVE status), from the menu of the disk, select Manage migration and click Cancel migration.
7. In the adjacent browser tab, open the project to which you want to migrate disks.

OpenStack CLI

1. Open the OpenStack CLI.

2. Disconnect the disk from the cloud server:

   openstack server remove volume <server> <volume>

   Specify:

   • <server> — Server ID or name. The list can be viewed with openstack server list
   • <volume> — ID or disk name. The list can be viewed with openstack volume list

3. Create a request to move the disk to another project:

   openstack volume transfer request create <volume>

4. If you want to transfer multiple disks at once, enter:

   openstack volume transfer request create <volume_1> <volume_2> <volume_3>

5. Save from the output of the command:

   • auth_key — key value;
   • id — Transfer ID.

6. Optional: to cancel the transfer, delete the request:

   openstack volume transfer request delete <id>

7. Configure authorization in the OpenStack CLI for another project.

8. Confirm the transfer:

   openstack volume transfer request accept --auth-key <auth_key> <id>
