The Document Foundation has released a white paper to help organisations migrate to LibreOffice.
According to the white paper, a migration to Free Software - and especially to LibreOffice - should follow a "carefully crafted" change management process, which needs to handle not only the technical aspects...
(which the foundation says are actually the easiest ones to cope with)
... but also the barriers met when breaking long-term working habits.
LibreOffice employs use of the ODF (Open Document Format).
ODF is a standard document format that is now claimed (by the Document Foundation) to enjoy support by the largest number of desktop software suites on the planet (including Microsoft Office).
NOTE: LibreOffice templates uses only free fonts available on every OS. These can be installed independently from any software package and thus foster interoperability between GNU/Linux, MacOS and Windows users as documents maintain their original layout on every platform.
According to a press statement, "LibreOffice offers the largest set of import filters for
proprietary document formats (including Microsoft Office, Publisher, Visio and Works, plus Corel Draw, Lotus 1-2-3 and WordPro, Quattro Pro and WordPerfect), and thus protects user investments in legacy applications, while providing a migration path to ODF."
