# Set-RubrikVgfAutoUpgrade

## SYNOPSIS

Updates the Volume Group format auto upgrade settings on a Rubrik cluster

## SYNTAX

```
Set-RubrikVgfAutoUpgrade [[-migrateFastVirtualDiskBuild] <String>]
 [[-maxFullMigrationStoragePercentage] <Int32>] [[-Server] <String>] [[-api] <String>] [<CommonParameters>]
```

## DESCRIPTION

The Set-RubrikVgfAutoUpgrade cmdlet is used to update the Volume Group format auto upgrade settings to a Rubrik cluster. There are two configurations available:

* 'migrateFastVirtualDiskBuild', or 'AutoUpgradeMode', is a string-type

  flag that controls the use of the fast VHDX builder during

  volume group migration.

  When the value of the flag is 'Error-Only,'

  the volume group uses the fast VHDX builder when a pre-5.1 volume group

  backup operation fails during the fetch phase.

  When the value of the flag

  is 'All,' the volume group uses the fast VHDX builder the next time the

  volume group is backed up.

  Any other value disables the fast VHDX builder.

  This flag is used in combination with the maxFullMigrationStoragePercentage

  value.
* 'maxFullMigrationStoragePercentage', is an integer which specifies a

  percentage of the total storage space.

  When performing a full volume group

  backup operation would bring the total used storage space above this

  threshold, the cluster takes incremental backups instead.

  This value is

  used in combination with the migrateFastVirtualDiskBuild flag.

## EXAMPLES

### EXAMPLE 1

```
Set-RubrikVgfAutoUpgrade -migrateFastVirtualDiskBuild 'All'
```

This will set the cluster configuration to automatically upgrade format for all Volume Groups.

### EXAMPLE 2

```
Set-RubrikVgfAutoUpgrade -migrateFastVirtualDiskBuild 'Error-Only'
```

This will set the cluster configuration to automatically upgrade for Volume Groups that have a failure during the last backup.

### EXAMPLE 3

```
Set-RubrikVgfAutoUpgrade -migrateFastVirtualDiskBuild 'None'
```

This will set the cluster configuration to not automatically upgrade format for any Volume Groups.

### EXAMPLE 4

```
Set-RubrikVgfAutoUpgrade -maxFullMigrationStoragePercentage 70
```

This will set the cluster configuration to allow automatic upgrade only when the projected cluster space usage after upgrade does not exceed 70% of total cluster storage.

### EXAMPLE 5

```
Set-RubrikVgfAutoUpgrade -migrateFastVirtualDiskBuild 'Error-Only' -maxFullMigrationStoragePercentage 70
```

This will set both configurations on the cluster.
