Data Migration in Sunderland
Moving a Sunderland organisation's data from an old system into a new one. Migration is where system replacements fail, and almost always for the same reason: the old data is messier than anyone believed, and nobody found out until the week the new system was meant to go live.
Why this comes up
The problem
A new system is being implemented and the migration is a line on the plan with no detail. Nobody has looked at the old data closely enough to know what state it is in.
What you get
What we deliver
- Source data profiled early, so the real state is known while there is time to act
- Mapping documented field by field, including what has no destination
- Cleansing and deduplication decisions made explicitly rather than by whoever runs the script
- Trial migrations run repeatedly, since the first one is never right
- Reconciliation proving what moved — counts and values matched, not assumed
- A rollback plan, because cutover is the point of no return without one

Data Migration in Sunderland — common questions
- Why do migrations go wrong so often?
- Because data quality is discovered late. Duplicate customers, dates in three formats, notes fields holding structured information — none of it is visible from a schema. Profiling the actual data early is the single highest-value step in the whole project.
- Should we migrate everything?
- Usually not. Old records nobody has opened in five years cost effort to map and clean, and often carry data protection obligations. Archiving rather than migrating is frequently the better answer, provided the archive stays accessible.
- How many trial runs are needed?
- More than one, always. The first reveals problems, the second reveals the problems your fixes introduced, and the last should be a rehearsal that runs clean against a full copy — timed, so cutover duration is known rather than hoped for.
- How do we prove the migration worked?
- Reconciliation before anyone signs off: record counts, financial totals and sampled records compared between systems. Without it, discrepancies surface weeks later when the old system has been decommissioned and the evidence is gone.
- Do you work with businesses across Tyne and Wear?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout North East, including Sunderland and the surrounding Tyne and Wear area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Sunderland businesses do you usually work with?
- Automotive supply chain integration and stock systems where uptime requirements are set by the production line. Beyond that we work across Automotive, Manufacturing, Software, Logistics and Higher Education.
- Do you cover the areas around Sunderland?
- Yes — we work throughout North East, including Newcastle, Durham, York. Sunderland is an urban area of roughly 270,000+, and we take on work across the wider Tyne and Wear region rather than the city boundary alone.
