This document discusses version control options in Microsoft Dynamics AX, including MorphX VCS. It describes how MorphX VCS enables source code control through check-in/check-out and change history. MorphX VCS is intended for smaller development teams of 1-10 developers, unlike Visual SourceSafe and Team Foundation Server which are aimed at larger teams of 5+ developers. The document compares requirements and features of classic version control, MorphX, and other options like concurrent development support and change tracking.
