What system migration really means

System migration is not just about one system or data warehouse: it is about the complete transition of applications, data and processes to a modern environment - be it on-premise, cloud, microservices or hybrid landscapes.

This step brings new performance, modern functionality and long-term cost savings - but also harbors risks such as downtime, data loss and complexity traps. Only a planned approach can prevent expensive surprises.

‍

Frequent challenges during migrations

We regularly experience this in our projects:

• Silos instead of an overall system: applications, databases and interfaces are isolated - there is no holistic view.
• Incomplete data migration leads to inconsistencies and unnecessary legacy data.
• Missed stakeholder involvement: Migrations must be accompanied strategically - technically and organizationally.
• Change management underexposed: Employees are involved too late - the roadmap looks good, but without them it falls flat .

Our 6-phase approach at DI Experts

1. Analysis & Scope
   We start with a complete assessment: systems, data flows, functions and affected departments.
2. Stakeholder and governance setup
   CIO, specialist departments and IT manage the project together. Roles, responsibilities and communication channels are clear from day 1.
3. Data quality & pre-tests
   Data is cleansed, migrated and connected early via test migration - reduced "blast radius" in live operation.
4. Step-by-step migration ("chicken-little") or hybrid roadmap
   Migrations are implemented in clear stages, not in a big bang, in order to keep risks manageable.
5. Change & Adoption
   A communication and training plan accompanies the entire process - visibility ensures acceptance .
6. Cut-over, testing, roll-out and stabilization
   "Soft go-lives", monitoring, support structures - how to make the live changeover safe and controlled
