# Switch-VBRNASInstantRecoveryMigration

## Short Description
Starts the manual switchover for completing the migration to production after you perform the instant file share recovery.

**Product Edition**: Standard, Enterprise, Enterprise Plus, Veeam Universal License

## Syntax
```
Switch-VBRNASInstantRecoveryMigration [-InstantRecoveryMigration] <VBRNASInstantRecoveryMigration> [<CommonParameters>]
```

## Detailed Description
This cmdlet starts the manual switchover for completing the migration to production after you perform the instant file share recovery.

During migration to production, Veeam Backup & Replication moves to the production site not only content of the initial file share, but also incremental changes made by users in the mounted file share. When incremental changes are being moved, the mounted share is not available to users. This stage is called a switchover. The switchover may take some time, so ensure you properly plan when it is performed.

### Starting Manual Switchover

This example shows how to define settings for performing a switchover in the scheduled mode.

```
$nasInstantRecovery = Get-VBRNASInstantRecovery -Id "42696B53-6FEC-4148-9354-AA9E4B52DED9"
$migration = Get-VBRNASInstantRecoveryMigration -InstantRecovery $nasInstantRecovery
Write-Output "Start manual switchover for migration sessions of instant restore for file backups."
Switch-VBRNASInstantRecoveryMigration -InstantRecoveryMigration $migration
```

Perform the following steps:

1. Run the [`Get-VBRNASInstantRecovery`](get-vbrnasinstantrecovery.md) cmdlet. Specify the `Id` parameter value. Save the result to the `$nasInstantRecovery` variable.
2. Run the [`Get-VBRNASInstantRecoveryMigration`](get-vbrnasinstantrecoverymigration.md) cmdlet. Set the `$nasInstantRecovery` variable as the `InstantRecovery` parameter value. Save the result to the `$migration` variable.
3. Run the `Write-Output` cmdlet. Specify the output wording.
4. Run the `Switch-VBRNASInstantRecoveryMigration` cmdlet. Set the `$migration` variable as the `InstantRecoveryMigration` parameter value.
