PostgreSQL Migration in Doncaster
Migrating Doncaster organisations onto PostgreSQL, where the schema moves easily and the procedural code does not. Years of business logic written into stored procedures and triggers in another database's dialect has to be translated or relocated — and it is usually undocumented, so establishing what it does is most of the work.
Why this comes up
The problem
The tables migrate cleanly and four hundred stored procedures contain logic nobody has read since they were written.
What you get
What we deliver
- Procedural code inventoried and assessed for what is still in use
- Logic relocated to the application where it does not belong in the database
- Remaining procedures translated with behaviour verified, not just syntax
- Case sensitivity handled, since identifier folding differs between systems
- Data types mapped deliberately where the source has no direct equivalent
- Parallel running with reconciliation before the source system is retired

PostgreSQL Migration in Doncaster — common questions
- Why is stored procedure code the hard part?
- Because it is business logic in a dialect-specific language with no documentation. Translating the syntax is mechanical; establishing what a procedure is meant to do, whether anything still calls it and whether the new version behaves identically is not.
- Should logic move out of the database?
- Where it is genuinely application logic, yes — migration is a rare opportunity to relocate it. What belongs in the database is what benefits from being close to the data, and a great deal of procedural code is there for historical reasons rather than good ones.
- What surprises people about identifiers?
- Case handling. PostgreSQL folds unquoted identifiers to lower case where some systems fold to upper, so code that mixes quoted and unquoted references can produce objects that appear to exist and cannot be found — a small difference with confusing symptoms.
- How long should both systems run?
- Until reconciliation across a full business cycle is clean. That period is what proves the translated logic produces identical results under real conditions, and it gives the teams depending on the data time to raise discrepancies while the source is still available.
- Do you work with businesses across South Yorkshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Yorkshire & the Humber, including Doncaster and the surrounding South Yorkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Doncaster businesses do you usually work with?
- Warehouse management, routing and proof-of-delivery systems for distribution operators working at national scale. Beyond that we work across Logistics, Rail Engineering, Manufacturing, Retail and Aviation.
- Do you cover the areas around Doncaster?
- Yes — we work throughout Yorkshire & the Humber, including Sheffield, Wakefield, Leeds. Doncaster is an urban area of roughly 310,000+, and we take on work across the wider South Yorkshire region rather than the city boundary alone.
