TAP Migration for Utilities: Data migration that’s verified upon arrival
Many municipal utilities and utility companies are facing the transformation of their existing billing systems—from SAP IS-U to established industry solutions such as Wilken.
In the context of the SAP IS-U replacement and the migration to the Thüga Billing Platform (TAP), the real challenge therefore lies not in the technical transfer alone, but in the structured migration of data, rules, and processes to a standardized target architecture.
That is why cimt provides targeted support to municipal utilities at the intersection of business units, legacy systems, and the TAP target vision—with a focus on migration, validated, and verifiable.

Our Approach: Six Phases to a Robust TAP Migration
From our perspective, the primary task is not initially about technology transfer, but rather about the structured preparation and migration of your existing data and process landscape into the TAP target architecture. Our phase-based approach therefore takes you from analysis and mapping through transformation and validation to go-live—all of which is business-aligned, technically robust, and comprehensively documented.
1. Analysis & Discovery
First, establish transparency regarding data objects, source structures, special cases, and process logic critical to migration.
2. Mapping & Target Model
Next, define business and technical mapping, selection, and transformation rules to serve as a robust foundation for migration and validation.
3. Transformation & Data Preparation
Next, extract, clean, and harmonize the data, and convert it into transfer structures suitable for migration.
4. Test Migrations & Validation
Then use technical and business test cycles to gradually stabilize the mapping, data quality, and migration logic.
5. Production Preparation & Cutover
Next, prepare approvals, migration windows, escalation procedures, and fallback scenarios to ensure a controlled transition.
6. Production Migration & Hypercare
Finally, support the go-live and stabilize the target system during the hypercare phase—through monitoring, error tracking, and structured corrective actions.

Frequently Asked Questions About TAP Migration
How long does a TAP migration take, and when should we start?
The project duration depends heavily on the complexity of your legacy systems and the quality of your data, but often ranges from several months to over a year. Given that support for SAP IS-U will end by 2030 at the latest, it is advisable to start the project early to avoid capacity bottlenecks in the market.
By when must SAP IS-U be replaced—and why?
Vendor support for SAP IS-U will end no later than the end of 2030; after that, there will be no more updates or maintenance. Anyone who has not migrated by then risks security vulnerabilities, failure to comply with regulatory requirements, and system outages.
TAP or S/4HANA—which solution is right for our company?
The right choice depends on factors such as cloud vs. on-premises strategy, business model, and existing IT infrastructure. That’s why we analyze your current situation and identify which solution—or even a hybrid approach—makes the most sense for you, both economically and technically.
How does a TAP migration using cimt work?
We support you every step of the way—from data cleansing and migration preparation to integrating your legacy systems, through to go-live and subsequent operational support. We place particular emphasis on high data quality, as this is crucial to the project’s success.
