Data Migration Cost Estimate
This is a practical guide to building a cost estimate for a data migration project — a forecast of the money required to complete the work, adapted to the realities of moving data from legacy systems into a new platform.
What a Cost Estimate is
A cost estimate is a forecast of the money required to complete the work. For the full concept and how it works in general, see Cost Estimation. On a data migration project it plays the same role, tuned to this kind of work.
Why it matters for a Data Migration project
Data Migration projects live or die on moving data from legacy systems into a new platform. A well-built cost estimate gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how data migration projects drift into avoidable delay and cost.
What to include
- Labour costs
- Material/equipment costs
- Indirect costs
- Contingency
- Estimate basis and assumptions
Data Migration-specific considerations
Tailor the cost estimate to the risks that most often derail data migration projects:
- Data quality and lineage
- Field mapping errors
- Reconciliation and cutover
Example
On a real data migration project, the cost estimate would be shaped by moving data from legacy systems into a new platform. In particular, it should explicitly account for the project’s biggest risks — data quality and lineage, field mapping errors, reconciliation and cutover — rather than treating them as afterthoughts.
