`<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 setting of the Quick Migration session of FCDs.

## Examples

::: example
### Example 1. Starting Quick Migration of all FCDs

This example shows how to starts Quick Migration of all FCDs. The cmdlet will perform migration with the following settings:

- The cmdlet will migrate FCDs that have been recovered within the `49664A5F-9C55-4A1F-8E6A-1CD5705A684B` FCD recovery session.
- The cmdlet will migrate FCDS to the `VeeamDatastore` target datastore.

```
$fcdInstantRecovery = Get-VBRFCDInstantRecoverySession -Id "49664A5F-9C55-4A1F-8E6A-1CD5705A684B"
$server = Get-VBRServer -Name "tech.local"
$datastore = Find-VBRViDatastore -Server $server -Name "VeeamDatastore"
Start-VBRFCDInstantRecoveryMigration -Session $fcdInstantRecovery -TargetDatastore $datastore
```

Perform the following steps:

1. Run the [`Get-VBRFCDInstantRecoverySession`](get-vbrfcdinstantrecoverysession.md) cmdlet. Specify the `Id` parameter value. Save the result to the `$fcdInstantRecovery` variable.
2. Get the datastore:

   1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
   2. Run the [`Find-VBRViDatastore`](find-vbrvidatastore.md) cmdlet. Specify the `Server` and `Name` parameter values. Save the result to the `$datastore` variable.

3. Run the `Start-VBRFCDInstantRecoveryMigration` cmdlet. Set the `$fcdInstantRecovery` variable as the `Session` parameter value. Set the `$datastore` variable as the `TargetDatastore` parameter value.

### Example 2. Starting Quick Migration of Specific FCDs

This example shows how to starts Quick Migration of the `disk1` and `disk2` FCDs. The cmdlet will perform migration with the following settings:

- The cmdlet will migrate FCDs that have been recovered within the `49664A5F-9C55-4A1F-8E6A-1CD5705A684B` FCD recovery session.
- The cmdlet will migrate FCDS to the `VeeamDatastore` target datastore.

```
$fcdInstantRecovery = Get-VBRFCDInstantRecoverySession -Id "49664A5F-9C55-4A1F-8E6A-1CD5705A684B"
$server = Get-VBRServer -Name "tech.local"
$datastore = Find-VBRViDatastore -Server $server -Name "VeeamDatastore"
Start-VBRFCDInstantRecoveryMigration -Session $fcdInstantRecovery -TargetDatastore $datastore -MountedDiskNames ("disk1", "disk2")
```

Perform the following steps:

1. Run the [`Get-VBRFCDInstantRecoverySession`](get-vbrfcdinstantrecoverysession.md) cmdlet. Specify the `Id` parameter value. Save the result to the `$fcdInstantRecovery` variable.
2. Get the datastore:

   1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
   2. Run the [`Find-VBRViDatastore`](find-vbrvidatastore.md) cmdlet. Specify the `Server` and `Name` parameter values. Save the result to the `$datastore` variable.

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

   - Set the `$fcdInstantRecovery` variable as the `Session` parameter value.
   - Set the `$datastore` variable as the `TargetDatastore` parameter value.
   - Specify the `MountedDiskNames` parameter values.

### Example 3. Starting Quick Migration of all FCDs and Applying Specific Storage Policy

This example shows how to starts Quick Migration for all FCDs and apply the `Virtual SAN Default` storage policy to these FCDs. The cmdlet will perform migration with the following settings:

- The cmdlet will migrate FCDs that have been recovered within the `49664A5F-9C55-4A1F-8E6A-1CD5705A684B` FCD recovery session.
- The cmdlet will migrate FCDS to the `VeeamDatastore` target datastore.

```
$fcdInstantRecovery = Get-VBRFCDInstantRecoverySession -Id "49664A5F-9C55-4A1F-8E6A-1CD5705A684B"
$server = Get-VBRServer -Name "tech.local"
$datastore = Find-VBRViDatastore -Server $server -Name "VeeamDatastore"
$storagePolicy = Find-VBRViStoragePolicy -Server $server -Datastore $datastore -Name "Virtual SAN Default"
Start-VBRFCDInstantRecoveryMigration -Session $fcdInstantRecovery -TargetDatastore $datastore -StoragePolicy $storagePolicy
```

Perform the following steps:

1. Run the [`Get-VBRFCDInstantRecoverySession`](get-vbrfcdinstantrecoverysession.md) cmdlet. Specify the `Id` parameter value. Save the result to the `$fcdInstantRecovery` variable.
2. Get the datastore:

   1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
   2. Run the [`Find-VBRViDatastore`](find-vbrvidatastore.md) cmdlet. Specify the `Server` and `Name` parameter values. Save the result to the `$datastore` variable.

3. Run the [`Find-VBRViStoragePolicy`](find-vbrvistoragepolicy.md) cmdlet. Specify the `Server`, `Datastore` and `Name` parameter values. Save the result to the `$storagePolicy` variable.
4. Run the `Start-VBRFCDInstantRecoveryMigration` cmdlet. Specify the following settings:

   - Set the `$fcdInstantRecovery` variable as the `Session` parameter value.
   - Set the `$datastore` variable as the `TargetDatastore` parameter value.
   - Specify the `MountedDiskNames` parameter values.
