Migration using Hystax Migration

You can migrate your resources to VK Cloud using the Hystax Acura Migration service without suspending applications. You can transfer resources from both virtual and physical platforms.

This instruction will help you migrate your resources to VK Cloud using the Hystax Acura Migration service using the example of the Ubuntu-MR VM with the Ubuntu 18.04 operating system.

By using the Hystax Acura Migration service, you agree to the license agreements of Marketplace and Hystax Acura Migration.

1. Register at VK Cloud.

2. Configure two-factor authentication (2FA) for the account on whose behalf the restored infrastructure will be deployed.

3. Create a VM for which recovery will be applied. As part of the quick start, the Ubuntu-DR VM with the Ubuntu 18.04 operating system will be used.

4. Connect Hystax Acura Migration service.

   Wait for the installation to complete — a link with a username and password will be sent to your email. The service will be deployed at https://migration.mcs-cloud.ru (Hystax Acura personal account).

1. Log in to Hystax Acura personal account using the received username and password.

2. Click the Install replication agents button.

3. In the “Agent selection” step, select Linux and click Next.

4. At the “Agent settings” step, specify the parameters:

   • Machines group: Default.
   • Select target Linux distribution: Debian/Ubuntu (.deb package).
   • Snapshot driver deployment type: DKMS.

5. Click the Next button.

6. Install the agent on the target VM, following the instructions for the Ubuntu distribution.

   After installing the VM agent, Ubuntu-DR will appear on the main page of Hystax Acura personal account with Discovered status.

7. Expand the Ubuntu-DR VM menu in the Machines Groups list and select the Start Replication option.

8. Wait for the operation to complete — the VM status will change to Synced.

1. Click the Create Migration plan button.

2. In the Name field, specify the name of the plan MR-plan.

3. Go to the Expert tab and click Generate Migration Plan from all machines button.

   A JSON file with the Ubuntu-MR VM will be generated.

4. Adjust the plan according to the requirements for VM recovery after failures:

   • In the subnet_id parameter, specify the network ID for the Ubuntu-DR VM.
   • In the flavor parameter, specify the name of the VM template, specify it using the openstack flavor list command.

   Detailed description of the parameters in the official documentation Hystax Acura.

5. Click the Save button.

1. Go to Migrate.

2. Select the MR-plan plan and click Next button.

3. In the Cloud Site Name field, specify the value VK-Cloud-infra and click Run migration button.

   The migration process will begin.

   • If the process completes successfully, VK-Cloud-infra will appear in the Cloud Site block with Active status.

   • If the process ended with errors, restart it:

     1. In the Cloud Sites block, click the Delete button for the process that failed and confirm the deletion.
     2. In the Migration plans block, for the MR-plan plan, click the Edit button.
     3. Make the necessary changes (in basic or expert mode).
     4. Click the Save button.
     5. Restart the plan.

Find the added VM in VK Cloud (<project PID>_cloud_agent), perform arbitrary operations on it.

Running VMs consume computing resources. If you don't need them anymore:

• Delete Ubuntu-MR VM, added to Hystax Acura personal account.
• Delete (detach) the backup infrastructure VK-Cloud-infra via Hystax Acura personal account.
• Delete floating IP address if it was created during migration.
