Proprietary Software to Open Source - Migration Approach
As more and more IT and ISV executives understand the power and promise of open source, proprietary software companies are starting to adopt the open source model. I quoted this phenomena as 'Opening Up - Who, When, What' in one of my presentations in May 2004. Since then, Ingres, Open Solaris, and many other commercial products have been open sourced. Recent announcements on Google's Free Urchin (free software, not open) and Sun's PostgreSQL support stress the importance of 'Software Delivered As A Service (SAAS)'. Larry Augustin's editorial describes why open source model is better very well.
Just in the last week, 3 proprietary software companies informally discussed with me on how to open source their products. I suggested the following migration approach and thought would share the same for wider community consumption.
