Database Migration · Chichester
Database Migration in Chichester
Moving a Chichester business's data from one platform to another — off an end-of-life server, out of Access or a spreadsheet, between cloud providers, or from one engine to another. Rehearsed on real volumes first, so the live run is a repeat of something that already worked rather than an experiment.
Why this comes up
The problem
Migrations fail on the data nobody looked at: duplicates, blank required fields, dates in three formats, encodings that break on the one record containing an accented name. None of it appears in a sample.
What you get
What we deliver
- A profile of the source data, including the quality problems nobody knew were there
- Field-by-field mapping agreed with you before anything moves
- Rehearsal runs on full production volumes, timed so the real window is known not guessed
- Reconciliation counts and checksums proving what arrived matches what left
- A cutover plan with a rollback that stays available until you sign off
- The old system kept readable for an agreed period after the switch

Thirty minutes, no charge, no sales script. You leave with a written summary of what database migration would actually involve — whether or not you use us.

Database Migration in Chichester — common questions
- How long will we be offline?
- The rehearsal tells you, which is the main reason to do one. Small datasets can move inside a maintenance window; large ones usually need a replication approach that keeps both systems in step until the final switch takes seconds.
- What happens to bad data?
- It gets found in the profiling stage and you decide: clean it, migrate it as-is, or exclude it with a record of what was left. What we will not do is silently drop rows that fail validation, which is how a migration finishes on time and loses six years of history.
- Can we go back if it goes wrong?
- Yes — the source stays intact and untouched until you have signed off. A migration without a rollback is a bet, and it is not one we ask clients to take.
- Our data is in spreadsheets. Can you still migrate it?
- Yes, and it is common. Spreadsheets carry more inconsistency than databases because nothing was ever enforced, so the profiling stage does more work — but the process is the same.
- Do you work with businesses across West Sussex?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Chichester and the surrounding West Sussex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Chichester businesses do you usually work with?
- Booking and ticketing for arts and marine operators, built to survive a season that carries the whole year. Beyond that we work across Tourism & Heritage, Agriculture, Marine, Arts & Culture and Retail.
- Do you cover the areas around Chichester?
- Yes — we work throughout South East, including Southampton, Portsmouth, Brighton. Chichester is an urban area of roughly 30,000+, and we take on work across the wider West Sussex region rather than the city boundary alone.
