Almost everyone’s first data migration feels chaotic. The interesting question is why, because the answer points straight at the fix.
The cause is rarely a lack of talent. It is that migration is handed to capable people as an exception rather than a discipline. They are asked to deliver something unfamiliar, at speed, with no agreed structure, and the early phase becomes a scramble to work out the basics while the clock runs.
In practice the chaos shows up as a few recurring symptoms:
- ownership is ambiguous, so decisions stall or get made by whoever is loudest,
- data quality concerns are raised but cannot be judged, because there is no agreed standard,
- the plan is built on hope, then repeatedly reworked as reality intrudes,
- effort spikes near cutover, when problems that were always present finally become undeniable.
From a business standpoint, that is not just an uncomfortable experience. It is avoidable cost, slipped dates, and eroding confidence in the programme.
Structure is the remedy, and it does not require heroics
- Make responsibility explicit early. Decide who owns each data area before commitments are made, so the Responsibility Gap between business and supplier is closed rather than discovered.
- Turn quality into something testable. Data Quality Rules convert vague worries into specific, measurable checks the team can act on.
- Sequence discovery before commitment. Understand the landscape first, then plan, so the schedule reflects evidence rather than optimism.
- Use shared artefacts as the team’s memory. Consistent documents carry decisions and risks forward, so the team improves instead of relearning.
None of this removes the difficulty of a first migration. It removes the chaos around the difficulty, which is where most of the avoidable cost hides.
