Successful Re-Platforming

Every software product must one day be rebuilt. The hard part is not the new platform. It is moving your customers with you.

Successful Re-Platforming: A Journey is a practical, research-based guide to product replatforming and customer migration in B2B software. Written by magnus billgren of tolpagorni thoughts, together with a research group of product leaders, CTOs and software engineering professors, it shows how companies rebuild their products without losing their customers.

Inside you will find:
• Four real success stories: a migration sold as a product, a new product built with seven lead customers, a shrinking business turned market leader, and a silent backend rebuild.
• Ten precepts for product transitioning, from "the trigger is not the goal" to "clarity before comfort".
• Six vital activities and six models for planning migration waves, readiness, the business case and a clear finish line.
• The triple-tech development problem: why the legacy product, the new platform and the data migration compete for the same people and budget.

Product transitioning is two journeys under one strategy: rebuilding the product and moving every customer, with their data, integrations and ways of working. As AI makes code faster to rebuild, the customer migration becomes the whole game.

For product managers, CPOs, CTOs and software teams facing a platform migration, legacy modernization, SaaS transition or other technology upgrades.
