When replacing legacy IT systems, during mergers, or when consolidating data assets, customer data must be transferred into new structures. These data are often simply copied over — but this is precisely where risks lurk. Different data sources need to be standardised, duplicates and erroneous entries detected and cleansed. Economically relevant information must be documented in an audit-proof manner, and the migration must be completed in a short time frame to minimise downtime. What looks technically straightforward at first glance is in reality a complex and critical process.
Requirements for sustainable data migration
Completeness
All essential data content from the source systems must be preserved in the target system.
Speed
The migration must be executed in a short time so that downtime for both source and target systems is kept to a minimum.
Traceability
It must be possible to trace where the data originally came from; all processing steps must be traceable.
Formatting
The target system determines the formats required for migration. The incoming data must be converted accordingly.
Duplicate-free
Identical customers from different data sources, as well as duplicates, must be merged to create a unified view of the customer.
Robustness
The migration process must be thoroughly tested and should be robust for productive execution, so that unexpected delays and errors do not occur.

FAQ
Data migration is much more than simply “transferring” data. It provides an opportunity to clean and consolidate data. The data must be adapted to the structure of the target system. The entire process must be thoroughly tested to minimize data loss and avoid delays.
Through targeted data profiling, defined cleansing rules, and automated processes, incorrect, outdated, or duplicate data records are identified and cleansed. After automatic validation, migration data undergoes a manual review. This results in a consistent, up-to-date, and reliable database in the target system.
All migration steps are fully documented and logged. This ensures that the origin of the data and how it was transformed can be traced at any time. This is particularly important for business-critical data and data subject to audit.
By using automated processes and proven methods, the migration is efficiently planned and implemented. The goal is to complete the actual migration in as short a time frame as possible, thereby minimizing downtime for your systems. Typically, the production data migration—from exporting data from the source system, through preparation, to importing it into the target system—takes 1–2 days.
