The verdict in three sentences
A professional data migration when switching business software in Dublin costs between EUR 8,000 and EUR 35,000 in 2026, mapping, cleaning and controlled reload included. The realistic timeline is 4 to 10 weeks with a target error rate below 0.5% and guaranteed reversibility. It is your assurance against losing ten years of customer history in a risky copy-paste.
What a data migration covers
A serious migration is not just an export/import. It includes source and target schema analysis, field mapping, cleaning (duplicates, formats, empty fields), batch reload, validation and a rollback plan. The volume and quality of the original data determine the price.
| Scope | Volume / complexity | Timeline | Price EUR |
|---|---|---|---|
| Simple migration | < 10,000 records | 3-4 weeks | 8,000 - 14,000 |
| Standard migration | 10,000 - 100,000, medium mapping | 5-7 weeks | 14,000 - 24,000 |
| Complex migration | Multi-table, heavy history | 7-10 weeks | 24,000 - 35,000 |
| Critical migration | Regulated data + audit | 10-14 weeks | 35,000 - 55,000 |
A data-migration expert's day rate in Dublin sits between EUR 450 and 650 in 2026. A standard migration represents 25 to 45 person-days, including analysis, reload scripts, test cycles and client acceptance.
Managed migration or manual re-entry
Some teams attempt manual re-entry to save money. The maths rarely wins once volume exceeds a few thousand rows, because of errors and mobilised time.
| Criterion | Managed migration | Manual re-entry |
|---|---|---|
| Direct cost | EUR 8,000 - 35,000 | "Free" internal time |
| Error rate | < 0.5% | 3 - 10% |
| Timeline | 4 - 10 weeks | Unpredictable |
| Reversibility | Guaranteed | None |
| Cleaning included | Yes | Rarely |
| Team mobilisation | Low | Very high |
Manual re-entry of 50,000 records at a 5% error rate leaves 2,500 wrong rows in the new system, with a later correction cost often higher than the price of a managed migration. Guaranteed reversibility is a decisive safety net if something goes wrong on cutover day.
Mini case study
Sophie, operations director of a services SME in Dublin (60 employees), was switching business software after 9 years of use. Her history held 48,000 customer records and 210,000 activity lines. Manual re-entry by her team would have tied up 3 people for 6 weeks, about EUR 22,000 of internal time, with a high error risk.
She chose a standard managed migration at EUR 19,500, delivered in 6 weeks with a measured error rate of 0.3% and guaranteed reversibility. A cost comparable to internal time, but without tying up the team and with reliable data from day one. Cutover happened with no business interruption.
