"These guidelines have been designed to help public administrators decide whether a migration to OSS should be undertaken and describe, in broad technical terms, how such a migration could be carried out. They are based on practical experience of a limited number of publicly available case studies, and cover a wide range of management and technical concerns."

You can also download just the guidelines or the explanatory notes (both English PDF), or the comparison spreadsheet in Excel or OpenOffice format.
