Migrating Data Between Two Systems
Moving from an old system to a new one is one of the riskiest parts of any project, because the data is your business. A careful migration plan turns a nerve-wracking switch into a controlled, rehearsed event.
This article explains the process we follow to move your data accurately and with minimal disruption.
The Core Steps
- Map: match every field in the old system to its place in the new one.
- Cleanse: fix and deduplicate data before it moves.
- Migrate: transfer the data, transforming it to fit.
- Verify: check counts and samples to confirm nothing was lost or mangled.
Rehearse Before the Real Thing
We run the full migration into a test environment first, often several times, fixing issues at each pass. By the time we migrate for real, the process is proven and predictable.
Cutover and Fallback
- Choose a quiet window to minimise impact.
- Keep the old system available, read-only, as a safety net.
- Agree clear criteria for declaring the migration a success.
Frequently Asked Questions
Will we lose data in the move?
Our verification step exists precisely to ensure we do not. We reconcile record counts and spot-check content before signing off.
How long does a migration take?
It depends on data volume and quality. The rehearsals tell us exactly how long the real cutover will need.
