"Achieving Success in Banking Migrations: Steps and Strategies"
Sparda-Bank Baden-Württemberg Successfully Completes Core Banking Migration
In a significant milestone, Sparda-Bank Baden-Württemberg, the largest of the eleven Sparda-banks, has successfully transitioned to Atruvia's core banking system, agree21. This migration marks the second-to-last step in a mammoth project that aims to unify all Sparda banks under the same IT infrastructure.
The migration process, led by Atruvia, was a complex undertaking, involving the management of over 400,000 eBanking customers and 370,000 giro accounts. Stephanie Wachtarz, a project manager for migration and merger projects at Atruvia AG, emphasized the importance of good project management, the right participants, and a structured time and action plan for a successful migration.
A Phased Approach and Parallel Operations
The migration strategy adopted a phased approach, gradually migrating components or functions in waves rather than a "big bang" cutover. This approach reduced risk, allowed learning from early phases, managed complexity, and supported operational continuity. The migration team also ran the new core system alongside the legacy system during a coexistence phase, ensuring validation, smooth switchover, and quick rollback if needed.
Comprehensive Planning and Governance
Defining what data, systems, and processes were in scope and why, along with clear, measurable KPIs for migration success, aligned teams and stakeholders. Maintaining detailed inventories of datasets, dependencies, and stakeholder roles reduced surprises and kept the process aligned with business, compliance, and operational goals. Incorporating security architects into migration teams and embedding governance from the outset avoided costly rework and mitigated operational resilience risks.
Addressing Organizational Complexity
Coordination among mixed teams with diverse skills required transparent communication, clear decision rights, and change management emphasis. Building governance structures and approaching change in manageable increments prevented overload and adverse impacts on timeline or quality.
Support and Follow-up Care
Good customer communication was emphasized as key during the transition, with extensive communication campaigns beforehand and various support offerings provided. The migration team established processes and procedures to solve any arising problems as quickly as possible. After the migration, follow-up care began to smooth out all eventualities.
Key Learnings from Past Migrations
Atruvia has identified key learnings from past core banking migrations, including thorough planning, early employee involvement, transparent information policy, use of migration for standardization, digitalization, and automation, comprehensive on-site presence by Atruvia project staff in the first days after migration, and good project management with the right participants and a structured time and action plan.
The Road Ahead
Following the successful migration of Sparda-Bank Baden-Württemberg, the focus now shifts to the migration of the remaining five Sparda banks, with Sebastian Lotz, a project manager for migration and merger projects at Atruvia AG, leading the project management team. After the migration of Sparda-Bank West in October 2025, all eleven banks will have the same IT infrastructure, completing the mammoth project.
Despite the success of the migration, it is important to remember that no project is without its challenges. As Stephanie Wachtarz noted, "Unfortunately, it is not possible to avoid the odd hitch on the go-live date." Nevertheless, the cooperation between Sparda-Bank Baden-Württemberg and Atruvia has been praised as leading to an excellent cut-over result, demonstrating the effectiveness of the strategies employed.
