Parameters

1

Parameter

Required

Type

Description

NewDatabaseName

Required

System.String

Specifies the name of a new scale-out database that you are creating.

SourceDatabase

Required

Microsoft.SharePoint.PowerShell.SPDatabasePipeBind

The source scale-out database to move data from.

SourceServiceApplication

Required

Microsoft.SharePoint.PowerShell.SPServiceApplicationPipeBind

The service application in which the data move operation will take place.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

noteNote:

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

Confirm

Optional

System.Management.Automation.SwitchParameter

Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters

MoveLowerHalf

Optional

System.Management.Automation.SwitchParameter

Specifies whether to move the lower or the upper side of the data range from the source scale-out database. If this parameter is not specified, the default behavior is to move the upper side of the source scale-out database data range.

NewDatabaseCredentials

Optional

System.Management.Automation.PSCredential

Specifies the credentials to use when creating the scale-out database. These credentials will have owner permissions on the new scale-out database. If you do not provide a value, the credentials of the logged on user will be used.

NewDatabaseFailoverServer

Optional

System.String

Specifies the failover server name of the new scale-out database. If you do not provide a value, the new scale-out database does not have a failover server.

NewDatabaseServer

Optional

System.String

Specifies the name of the server of the new scale-out database. If you do not provide a value, the name of the default database server is used.

SourcePercentage

Optional

System.Int32

Specifies the percentage of data in the source scale-out database to move. If you do not provide a value, the default value, 50 percent, is used.

WhatIf

Optional

System.Management.Automation.SwitchParameter

Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters
