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.
