IBM is offering $20,000 to customers to switch from Microsoft Exchange to IBM"s Lotus Notes and Domino platform, part of a new "Migrate to the Penguin" program, which is part of IBM"s "Move2Lotus" program.
The move is because of many companies not switching because of the cost. But if IBM offers $20 for every Exchange license in a company (with a max of 1000 licenses), then a company would easily be able to switch.
IBM is also offering free educational and certification programs to exploit IBM expertise, and is offering a "Try before you buy" deal.
