Schedule a Full User Profile Import

Article
08/11/2012

It may be desirable to perform full profile imports on a regular schedule, possibly once a month or once a quarter. This would ensure picking up changes in the import connection rules (included containers and filters for example), and changes to the profile property schema (new properties and changes in mapping to existing properties).

The Central Administration interface only provides a means to schedule incremental imports.

A full import can be started through Central Administration on-demand by using the Start Profile Synchronization link, but this link does not provide for scheduling.

It is possible to schedule full imports using the Windows Server Task Scheduler and a Windows PowerShell script.

Create the Windows PowerShell script ExecuteFullImport.ps1 and associated configuration file ExecuteFullImport.xml. Place in the standard scripts folder of the server. (Source code below. Special credit goes to Brian Lalancette and the AutoSPInstaller project for foundational code included in this script, reference https://autospinstaller.codeplex.com. AutoSPInstaller is a fantastic script to build multi-server SharePoint 2010 farms.)
Create a schedule task. Start Menu > Administrative Tools > Task Scheduler;
or Run > taskschd.msc.
Right click the Task Scheduler Library node in the left pane, and select Create Task.
On the General Tab, enter the Name and Description.
On the Triggers Tab, click the New button, and then enter the desired schedule.
On the Actions Tab, select Start a program, enter PowerShell as the program/script, enter the script name ExecuteFullImport.ps1, and Start in put the directory containing the script and associated xml configuration file.
Optionally, modify the Conditions and Settings tabs’ configuration.
The script will run at the scheduled time. The PowerShell window remains open by default. Press any key to close the window.
