Microsoft's migration plan

C|Net | at | by Mike

A deal cinched Wednesday could help Microsoft tackle a long-standing problem: How to sell new software to customers reluctant to give up a 7-year-old version of Windows. Microsoft's acquisition this week of software and related patents from Connectix, a maker of virtual machine software, also gives the company a new weapon for its battle with rivals including Sun Microsystems and Oracle, analysts said Thursday.

Connectix makes software that lets a single computer perform like several independent computers running their own operating systems. It makes client software that permits Windows to run on a Macintosh, and server software that has yet to be released.
