`<CommonParameters>`

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see [ Microsoft Docs](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters?view=powershell-7).

## Output Object
The cmdlet returns the `CBackupSession` object that contains settings of the publish operation VM virtual disks to the production environment.

## Examples

::: example
### Publishing VM Virtual Disks to Production Environment

This example shows how to publish VM virtual disks to the production environment. The cmdlet will publish the disks to the datastore as it is defines in the mapping settings of the VM virtual disks.

```
$session = Get-VBRInstantRecovery
$backup = Get-VBRBackup -Name "Winsrv4515"
$restorepoint = Get-VBRRestorePoint -Backup $backup
$disks = Get-VBRViVirtualDevice -RestorePoint $restorepoint[3]
$mapping = New-VBRViDiskMigrationMappingRule -TargetVirtualDevice $disks
Start-VBRViInstantRecoveryDiskMigration -InstantRecovery $session -DiskMigrationMappingRule $mapping -Force -RunAsync
```

Perform the following steps:

1. Run the [`Get-VBRInstantRecovery`](get-vbrinstantrecovery.md) cmdlet.  Save the result to the `$session` variable.
2. Get the mapping settings of VM virtual disks:

   - Run the [`Get-VBRBackup`](get-vbrbackup.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$backup` variable.
   - Run the [`Get-VBRRestorePoint`](get-vbrrestorepoint.md) cmdlet. Set the `$backup` variable as the `Backup` parameter value. Save the result to the `$restorepoint` variable.
   - Run the [`Get-VBRViVirtualDevice`](get-vbrvivirtualdevice.md) cmdlet. Set the `$restorepoint` variable as the `RestorePoint` parameter value. Save the result to the `$disks` variable.

     The `Get-VBRRestorePoint` cmdlet will return an array of restore points. Mind the ordinal number of the necessary restore point (in our example, it is the fourth restore session in the array).

   - Run the [`New-VBRViVirtualDeviceMappingRule`](new-vbrvivirtualdevicemappingrule.md) cmdlet. Set the `$disks` variable as the `TargetVirtualDevice` parameter value. Save the result to the `$mapping` variable.

3. Run the `Start-VBRViInstantRecoveryDiskMigration` cmdlet. Specify the following settings:

   - Set the `$session` variable as the `InstantRecovery` parameter value.
   - Set the `$mapping` variable as the `DiskMigrationMappingRule` parameter value.
   - Provide the `Force` parameter.
   - Provide the `RunAsync` parameter.
