Luca Pacor
Last position:
ERP Program Manager at Fiserv
The client is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a global standard template.
The program also includes the migration and modernization initiative "RISE with SAP", which may involve migrating selected country installations to the SAP Private Cloud.
On the stakeholder side, the program's reporting line extends up to the company's board and the implementation partner's board.
Fiserv Germany's ERP landscape currently includes several non-standard SAP tools and applications that extend the ECC environment's functionality and often integrate with downstream systems. As part of the move to SAP S/4HANA, it is essential to assess the core functionality, integration points, and future viability of these applications to determine their alignment with the target architecture.
The focus of the role is to provide expert advice and assessment to define the scope, strategy, and roadmap for migrating Fiserv Germany's SAP ECC system to SAP S/4HANA.
SAP's recommended best practices are followed, and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.
This assessment forms the basis for a successful SAP S/4HANA transformation, ensuring alignment with industry best practices, regulatory compliance, and future scalability.
Migration strategy definition – evaluating available transition approaches based on business objectives, technical feasibility, and SAP best practices.
Technical readiness assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points, and infrastructure readiness for SAP S/4HANA.
Business process impact analysis – reviewing the latest business process documentation to define the scope and effort needed to implement required functions in SAP S/4HANA and identify process optimization opportunities.
Roadmap for non-SAP systems and applications – evaluating third-party and legacy applications for SAP S/4HANA integration and recommending consolidation, migration, or replacement strategies.
Deployment & implementation planning – defining a phased rollout approach, including project timelines, risk mitigation strategies, and key milestones aligned with business priorities.
The transformation is carried out in phases: the discovery phase leads to the explore phase, which then leads to the design phase and finally to the implementation phase.

About the technology
Token Ring in practice
Token Ring is a legacy LAN technology built for controlled access on a shared ring. It was common in IBM-based office networks, plant systems and older enterprise setups that still need stable, predictable links. Specialists handle audits, recovery work and migration planning.
Common tasks
- Trace ring breaks and repeater faults
- Review MAU, NIC and cabling issues
- Document legacy topology and handover points
- Plan replacement paths to Ethernet
Ecosystem and terms
Work often touches IBM Token Ring, IEEE 802.5, MAUs, Token Ring adapters and old network management tools. Strong professionals understand how stations pass the token, how priority works, and where a single bad link can affect the whole ring. They also know how to read old diagrams and vendor labels.
When companies bring in specialists
Companies usually need outside help when a Token Ring segment is unstable, undocumented or tied to older business systems. That is common in manufacturing, logistics and office networks in Germany, where legacy infrastructure may still support critical work. Freelance expertise helps because these tasks are narrow, urgent and often paired with migration decisions.
What strong professionals deliver
Good specialists do more than find the fault. They isolate the issue, verify the physical layer, confirm device behavior and leave clear notes for the next team. They are careful with change windows, test plans and rollback steps.
Skills that matter
- Legacy LAN troubleshooting
- IBM network hardware knowledge
- Cabling and signal path checks
- Migration planning toward Ethernet
- Clear documentation for support teams
Frequently asked questions
Not sure where to start with Token Ring? These answers cover the essentials.
Token Ring is mainly found in legacy LAN environments that still run older business systems, lab setups or industrial networks. Most new projects involve support, diagnostics or migration rather than new installation. If you have IBM Token Ring or IEEE 802.5 hardware in place, you need someone who can work safely with the old ring design.
Token Ring uses controlled token passing, while Ethernet relies on switched access and modern collision-free designs. In practice, Ethernet is easier to expand and support, which is why many companies moved away from Token Ring long ago. The value of Token Ring expertise today is usually in maintenance, recovery and migration work.
A strong Token Ring specialist should also know cabling, network hardware, legacy IBM environments and structured troubleshooting. Experience with MAUs, adapters, physical layer testing and documentation is often important. For migration work, knowledge of Ethernet replacement planning is a big plus.
For a simple cable or adapter check, moderate experience may be enough. For unstable rings, undocumented sites or systems tied to production, you want someone who has handled Token Ring fault isolation before. The older the environment, the more you should value practical repair experience over theory.
Some Token Ring tasks can be done remotely if the site has monitoring, clear diagrams and a local contact for physical checks. But ring faults, cabling issues and hardware swaps often need on-site access. In Germany, many teams use a hybrid setup: remote analysis first, then local intervention if needed.
Ask which Token Ring systems they have supported, how they diagnose ring faults, and whether they have worked with IBM Token Ring or IEEE 802.5 hardware. Also ask how they document findings and how they handle migration decisions. A good answer is specific, practical and focused on risk control.
A good Token Ring expert explains the failure path clearly, names the likely hardware points and suggests a safe test sequence. They should know how to work with old network diagrams, adapters and ring access units without guessing. Clear notes and careful change handling are good signs.
Companies in Germany still need Token Ring specialists where older IBM-based systems or plant networks remain in service. The work is often tied to ongoing operations, audits or a planned move away from legacy infrastructure. In many cases, the right freelancer is needed for a short, focused assignment rather than a long project.
