Natuvion study shows 71% of data transformations shift mid-project

New study reveals why the Greenfield vs. Brownfield debate is the #1 planning mistake in modern data migrations.

MUNICH, June 10, 2026 /PRNewswire/ -- The biggest risk in a large data transformation isn't choosing the wrong starting point: it's choosing a path which can't be changed. Deciding between a greenfield or brownfield approach feels like a strategic milestone. In reality and proved in the recent Natuvion Transformation Study 2026, conducted by the data transformation specialist Natuvion and NTT Data Business Solutions, it is often the first mistake in planning a migration. All too often, it is assumed that transformations can be planned perfectly from day one. In reality, they rarely are. The uncomfortable truth is that plans are very likely to change during the migration process. According to the 2026 Transformation Study 71 percent of companies change their migration approach mid-project.

The Natuvion Transformation Study also shows that 44% of large-scale transformations in the USA take between one and two years. In that window, everything is in motion: business models shift, regulatory requirements evolve, data environments change, and internal priorities pivot.

When the original plan no longer holds, a rigid strategy becomes a liability. Nevertheless, many organizations start with a binary choice: from a US perspective Greenfield (start fresh) was chosen by 17% and Brownfield (lift and shift) by 39%, compared to the global results of 34% for Brownfield and 20% for Greenfield. While this deceptive clarity seems helpful at kickoff, it is a dangerous illusion. Neither approach is natively designed to adapt when missing data, legacy complexities, or new compliance rules appear twelve months into the roadmap.

"When a strategy is too stiff to bend, it breaks. This leads to slipped timelines, budget hemorrhaging, and stalled innovation. The failure isn't a result of poor execution; it is a result of a decision that was too rigid to account for the "moving target" of modern business", says Joanne Lang CEO of Natuvion Americas. "The defining factor of a successful transformation isn't the initial plan. It's the capability to adapt that plan without starting over. This is where Selective Data Transition changes the game. It isn't a compromise; it is a strategic capability that allows companies to change direction during the project, ensure that data remains safe, accessible, and compliant, no matter how the mission changes."
