This document describes how to upgrade any number of devices converted by UDC from Universal Desktop OS 2 v5.11.200 or higher (UDC2) to Universal Desktop OS 3 10.02.120 (UDC3).

If you have version 5.11.200 or higher, you can upgrade directly to version 10. If you have version 5.11.100 or older, you need to update to version 5.11.200 or higher first. However, it is possible to combine these two steps; see Mass Upgrading Your Devices.
