ArcPad extension

ArcPad 10.2 and later releases include support for synchronization with ArcGIS Server feature services (version 10.2 and later only). This support is a replacement for synchronizing data between ArcPad and ArcGIS Server using the ArcPad extension for ArcGIS Server, which is now obsolete. To learn about synchronizing features between ArcPad and ArcGIS Server using feature services, see What is synchronization in the ArcPad Help.

Legacy:

ArcPad 10.2 and later releases also support 10.0 and 10.1 feature services; however, their functionality is limited. 10.0 feature services only support a full download of features. This means that when you synchronize with 10.0 feature services that contain a large number of records, performance may be slow. 10.1 feature services also only support a full download of features, but do add support for related tables and editor tracking.
