As part of its ongoing effort to lure customers off of IBM's Lotus Domino and Novell's Groupwise, and onto the Exchange Server messaging platform, Microsoft is refreshing its suite of Exchange migration tools. The suite, code-named Red Bull, will come out right before the annual Lotusphere conference in late January in Orlando. Red Bull is expected to include a comprehensive revamp of Microsoft's mail migration tools, and includes an application and analysis analyzer and a recoded Exchange-Notes Connector.
