Budimex moves from Notes to Microsoft Exchange as part of a corporate-wide technology initiative 


“Leveraging the close relationship of HP Spain with Global TMS ensured the best possible engagement. The entire team was able to meet our requirements for flexibility and frequent communications. Thanks to a team effort and Binary Tree solutions, our migration project was a great success.”

— Project Management Team, Budimex


Project Overview

Budimex was updating its communications platform as part of a corporate-wide technology initiative to transition all operating companies to the same messaging platform. In the case of Budimex, this meant a transition from IBM/Lotus Notes to Microsoft Exchange on-premises.

As a company devoted to high-profile infrastructure projects and committed to sustainable development and corporate social responsibility, smooth and uninterrupted communications are critical. Therefore, the project requirements included flexibility, consistent communications among all parties, coexistence, no disruption for its 2,600 users, and a gradual migration at the rate of 50 users per day.

With Binary Tree migration solutions in place, Budimex relied on its excellent long-standing relationships with HP Spain and Global TMS to manage the planning, coexistence, and migration throughout the project.

Collaboration, Communication and Flexibility

After its parent company, Ferrovial, had initiated the process of platform standardization, Budimex began looking at solutions that would quickly and easily transition its IBM/Lotus Notes environment to Microsoft Exchange—with no disruption to its 2,600 users.

Budimex needed to find partner companies that could be flexible, work with their project managers on a weekly basis, have an excellent support team, and offer tools that would complete the migration with no effect on user productivity. With assistance from partners HP Spain and Global TMS, Binary Tree’s CMT for Exchange and CMT for Coexistence were selected as the best solutions to make this transition.

CMT for Exchange offers migration throughput, transitional calendar workflow, and migration management, while CMT for Coexistence creates high-fidelity interoperability and preserves user workflow between IBM/Lotus Notes and Microsoft Exchange. This solution is ideal for a migration performed over a relatively long period of time, where coexistence between two platforms is a requirement, and where application remediation is necessary over time.

In the end, the project was successfully completed at the appropriate pace, on time, and with no adverse effects on user productivity. Now, Budimex is aligned with its parent company and its users are enjoying the benefits of its upgraded messaging platform.

Finding a Better Way to Migrate

Given these challenges, it became clear that Essex needed an automated solution as well as expertise in Exchange migrations. The company’s IT staff contacted their longtime consulting firm, Hott Solutions, which recommended Binary Tree’s E2E Complete software after a thorough evaluation of migration products. To complement the choice of E2E Complete, Hott Solutions also selected the Mail Attender product from Sherpa Software to assist with preparing the environment for the migration.

Preparing the Mail Environment for the Migration

Hott Solutions used the Mail Attender product to perform an in-depth analysis of the mailbox data prior to the migration. Mail Attender identified the mail attachments that exceeded Office 365’s 25GB limit and enabled the team to remove them from mailboxes and store them in separate repositories for future access.
