Deploying migrations

Deployment creates virtual machines on the target platform from the replicated data. During deployment, the system prepares the guest OS and starts the VMs.

If no replication has been performed, deployment cannot be started. You can run additional replications before deployment to reduce downtime when switching to the target environment.

You can deploy a migration automatically after replication or start deployment manually on the Deployments tab.

Prerequisites

Replication must be completed before deployment. It can run automatically after migration creation, as described in Creating migrations, or be started manually, as described in Replicating migrations.

To deploy a migration

On the Migrations screen, click the name of the required migration.
On the Deployments tab, click Create deployment.
In the Create deployment window, specify the VM name and configure the deployment options:
- Enable Clone disks to reuse existing disks for incremental synchronization. If disabled, disks are fully re-synchronized.
- Enable OS morphing to prepare the guest OS for the target platform by installing required drivers and removing source-specific components.
  
  This step can be skipped when migrating between platforms using the same hypervisor (for example, KVM to KVM).
- Enable Start target VMs after deployment to start target VMs when they are deployed.
Upload user scripts to run on the guest OS during deployment.
Click Deploy.

After deployment starts, virtual machines are created on the target platform. You can monitor the deployment progress and status in the deployment details.

To cancel a deployment

Canceling a deployment takes effect immediately and cannot be reversed.

On the Migrations screen, click the name of the required migration.
On the Deployments tab, click the ellipsis icon next to the ongoing deployment, and then click Cancel.
In the confirmation window, click Confirm.

To recreate a deployment

On the Migrations screen, click the name of the required migration.
On the Deployments tab, click the ellipsis icon next to the required deployment, and then click Recreate.

The deployment will be recreated with the preconfigured options.

To delete a deployment

On the Migrations screen, click the name of the required migration.
On the Deployments tab, click the ellipsis icon next to the required deployment, and then click Delete.
In the confirmation window, click Delete.
