MySQL to PostgreSQL Migration · Birmingham
MySQL to PostgreSQL Migration in Birmingham
Moving Birmingham systems from MySQL to PostgreSQL, where years of quietly bad data arrive all at once. MySQL has historically accepted what it was given — impossible dates, values silently truncated, types coerced without complaint — and PostgreSQL refuses all of it, so the migration surfaces every one of those records.
Why this comes up
The problem
The import fails on thousands of rows containing zero dates and values that were silently truncated.
What you get
What we deliver
- Data profiled before migration, so the invalid rows are known in advance
- A decision made per category of bad data rather than fixed row by row
- Types mapped deliberately, since the two systems differ in meaningful ways
- Case sensitivity addressed, as PostgreSQL treats identifiers differently
- Queries reviewed, because MySQL-specific syntax will not run unchanged
- Application behaviour tested, since stricter rejection surfaces latent bugs

Working in Birmingham
West Midlands
Birmingham is the UK's second city and its business base is broad rather than specialised, so projects here range from single-site hospitality systems to multi-region platforms for professional services firms.
Briefs range widely, but the recurring themes are multi-site operations needing one system instead of five, and professional services firms replacing spreadsheets with something auditable.

MySQL to PostgreSQL Migration in Birmingham — common questions
- Why does so much data fail to import?
- Because it was never valid. MySQL's traditional behaviour accepted zero dates, truncated overlong strings and converted types quietly, so a long-running database holds records that were always wrong and only now produce an error.
- How should bad data be handled?
- By category rather than individually. Grouping the failures — all zero dates, all truncated values — and deciding a rule for each is both faster and defensible, whereas correcting thousands of rows by hand invites inconsistency and takes far longer.
- Will our queries still work?
- Not all of them. MySQL-specific functions, backtick quoting and its looser grouping rules all need changing, and the differences are usually obvious errors rather than silent ones — which is inconvenient but considerably safer.
- What about case sensitivity?
- It catches people out. PostgreSQL folds unquoted identifiers to lower case and treats quoted ones exactly, so a schema created with mixed-case names from a tool can produce tables that must be quoted forever afterwards — worth settling deliberately at creation.
- Do you work with businesses across West Midlands?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout West Midlands, including Birmingham and the surrounding West Midlands area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Birmingham businesses do you usually work with?
- Briefs range widely, but the recurring themes are multi-site operations needing one system instead of five, and professional services firms replacing spreadsheets with something auditable. Beyond that we work across Professional Services, Manufacturing, Financial Services, Construction, Hospitality and Logistics.
- Do you cover the areas around Birmingham?
- Yes — we work throughout West Midlands, including Coventry, Wolverhampton, Derby, Leicester. Birmingham is an urban area of roughly 2,600,000+, and we take on work across the wider West Midlands region rather than the city boundary alone.
