Migrating from one ERP system to another is one of the most complex IT projects a company can tackle. Not because the technology is insurmountable, but because it simultaneously involves processes, data, people and systems that are at the heart of almost every business operation. A mistake in planning is paid for with months of delay or a go-live that becomes an operational emergency.
This guide is designed for business owners, CIOs, and IT managers who are facing or evaluating an ERP migration and want to understand how to manage it in a structured way, reducing risk without stopping business.
Why you migrate from an ERP system
The most common reasons for a company to migrate its ERP system are: end of vendor support (as in the case of SAP ECC losing mainstream support in 2027), inability to integrate the system with new technologies, unsustainable maintenance costs, inability of the system to support business growth, or the need to unify disparate systems after a merger or acquisition.
In all of these cases, ERP migration is an opportunity as well as a necessity-it is a time to redesign processes, clean up data, and build a stronger technology foundation for the years ahead. Read our specific guide on migrating to SAP S/4HANA if you are considering this transition.
The critical phases of an ERP migration
A well-managed ERP migration has distinct phases, each of which requires specific skills and attention:
- Assessment and business case: analysis of the current situation, definition of objectives, evaluation of options, and construction of the case for investment
- Target system selection: choosing the new ERP based on process, industry and size requirements
- Solution design: new system configuration, process redesign, customization management
- Data migration: one of the most critical steps-the quality of the migrated data determines the quality of the startup
- Testing and training: validation of the solution with key users and training on new procedures
- Go-live and stabilization: startup in production with intensive support and continuous monitoring
The main risks and how to mitigate them
Data quality: legacy system data are often inconsistent, duplicate, or incomplete. A cleanup and validation strategy must begin early, not during migration.
Scope creep: the tendency to add requirements during the project is the number one cause of budget and time overruns. A clearly defined scope at the outset, with a managed process for changes, is essential.
Underestimation of change management: people who are to use the new system must be involved from the beginning, not just in pre go-live training. For professional ERP consulting, this aspect is an integral part of the project.
Poorly planned cut-over: the time of the transition from the old to the new system is the most critical time in the entire project. It must be planned in detail, with clear rollback plans in case of problems.
How to choose the target ERP system
The choice of target ERP system should be based on objective criteria: suitability to process needs, scalability, total cost of ownership (TCO), partner ecosystem and vendor support. For medium and large Italian companies operating in complex industries, SAP S/4HANA is often the most comprehensive solution, with a certified partner ecosystem and an established track record.
