Introduction to the Long-Term Servicing Branch of System Center Configuration Manager
Applies to: System Center Configuration Manager (Long-Term Servicing Branch)
The Long-Term Servicing Branch (LTSB) of System Center Configuration Manager is a distinct branch of Configuration Manager that is designed as an install option available to all customers. However, it is the only option for customers who let lapse their Software Assurance (SA) or equivalent subscription rights for Configuration Manager.
Based on Configuration Manager version 1606, the LTSB has reduced functionality when compared to the Current Branch of Configuration Manager.

The Current Branch of Configuration Manager supports the following functionality that is not available when you use the LTSB:
- In-console updates that add new features and improvements.
- Support for newly released operating systems to use as site servers and clients.
- Use of a Microsoft Intune Subscription to support:
- Intune in a hybrid mobile device management (MDM) configuration

The LTSB is based on Current Branch version 1606. For product documentation use the Current Branch documentation, with caveats and limitations that are specific to the LTSB. Those caveats and limitations are identified in the following on-line topics:

Licensing overview for the LTSB
Customers with active Software Assurance (SA) on System Center Configuration Manager licenses, or with equivalent subscription rights as of October 1, 2016, have rights to use the October 2016 version 1606 release of System Center Configuration Manager. Customers with rights to System Center Configuration Manager on or after October 1, 2016, will find two licensed options upon installation: Current Branch and Long-Term Servicing Branch (LTSB).
Customers that have perpetual rights to System Center Configuration Manager, or that allow SA or subscription to lapse after October 1, can install the version of System Center Configuration Manager LTSB that is current at the time of lapse.
See System Center Configuration Manager licensing and branches for more information about licensing for Configuration Manager branches.
If you decide that the Configuration Manager LTSB is the correct branch for your environment, install a new LTSB site as part of a new hierarchy, or upgrade a System Center 2012 Configuration Manager site and hierarchy.
If you do not have installation media, see System Center 2016 documentation for information on how to get System Center 2016, which includes media you can use to install the System Center Configuration Manager LTSB.
