The Lotus Notes Era
In the early days of our existence,
Binary Tree ventured into the challenging and complex world of
email migration by creating products that facilitated change. In the mid-1990s, we developed and marketed a number of separate tools for migrating mail, calendar, and contacts migrated from a source system to Lotus Notes.
This approach initially satisfied the market need; however, it also proved challenging for customers who had multiple messaging environments in place, such as Outlook Express, MS Mail, and CC:Mail. In late 1998, while migrating a customer with a myriad of different email systems to Lotus Notes, we decided that the only rational solution was to create a comprehensive migration product. The migration challenges presented by our customers paved the way for us to create the Binary Tree Common Migration Toolkit (CMT).
Over the next four years, we continued to advance the capabilities of CMT and the names Binary Tree and CMT became some of the most recognizable names in the world of messaging migration, as we became a key enabler to organizations that were transforming their messaging and collaboration capabilities. Our list of customers was rapidly growing to include the “who’s who” of the corporate world.
Evolving to Facilitate Merger & Acquisition Integrations 
In the early 2000s, we recognized that the migration trend was beginning to expand beyond just migrations to Lotus Notes. Corporate mergers, acquisitions, divestitures, re-branding, and other events created a need for an enterprise-grade migration solution within Lotus Notes. So we developed the
CMT for Domains product so that customers going through a merger, acquisition or divestiture could streamline how they migrated, consolidated, or separated diverse Domino domains. While CMT for Domains focused on
Domino-to-Domino merger integration, our product line would eventually evolve to support
Domino-to-Exchange and
Exchange-to-Exchange merger integrations as well.
The Notes Exodus Era
Also in the early 2000s, another trend was slowly emerging: migrations to Microsoft Exchange. With IBM focusing less on Notes and Domino and diluting the Lotus brand and value, and Microsoft emphasizing Exchange and Outlook more as an enterprise messaging solution, some of our Notes migration customers approached us about a migration tool from Notes and Domino to Outlook and Exchange.
In response to the market demand, we created
CMT for Exchange, an enterprise-scale migration solution that met the needs and the requirements of end users and administrators alike. The combination of fidelity, scalability, and manageability made CMT for Exchange the product of choice for the largest Domino to Exchange migration ever performed, for one the largest global financial firms, which had over 180,000 users worldwide.
As our experience with migrations to Exchange grew, we learned that as enterprises embarked on Domino-to-Exchange migrations, they required extensive interoperability (or “coexistence”) between the two diverse systems so that their end-users would experience a highly functional and seamless transition process. While there were tools available for temporary
coexistence between Domino and Exchange, we aimed our sights on creating an enterprise-class coexistence solution. The result was
CMT for Coexistence. By the mid-2000s, the CMT product suite became a true enterprise messaging migration solution suite. In recognition of that fact, the abbreviation CMT was changed to stand for Complete Migration Technology.
