How to Add a State Migration Point Folder
Updated: November 1, 2013
Applies To: System Center 2012 Configuration Manager, System Center 2012 Configuration Manager SP1, System Center 2012 R2 Configuration Manager
In System Center 2012 R2 Configuration Manager, you add an operating system deployment state migration point folder by adding the folder description to the Directories embedded property list.
The folder description is a string that defines the following information.
Value | Description |
|---|---|
Directory | The name of the folder. |
MaxClients | The maximum number of clients supported. |
MinDiskSpace | The minimum disk space required. |
MinDiskSpaceUnit | The minimum disk space units. 1 - MB 2 - GB 3 - Percentage |
To add a state migration point folder
Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Make a connection to the state migration point resources section of the site control file.
Get the Directories embedded properties list.
Update the Directories embedded property with new folder.
Commit the changes to the site control file.
Example
The following example method adds a new folder to the state migration point.

For Each SCIComponent In SCIComponentSet
For Each vProperty in SCIComponent.PropLists

Next

vProperty.Values = directories
End If
Next
' Update the component in your copy of the site control file. Get the path
' to the updated object, which could be used later to retrieve the instance.
Set SCICompPath = SCIComponent.Put_( , context)
Next
