The UBS Wealth Management & Business Banking unit migrated its internal software development projects from the CM Synergy (formerly Continuus) change management system to Subversion. In this talk, we present organizational and technical aspects of the migration project. We show how existing development processes were adapted and how user acceptance for the new system was achieved. Furthermore, we discuss the technical challenges involved in the migration of a large number of CM Synergy repositories to Subversion.
