SQL Server to PostgreSQL Migration · Cambridge
SQL Server to PostgreSQL Migration in Cambridge
Moving Cambridge systems from SQL Server to PostgreSQL, where a difference in text comparison quietly changes results. SQL Server's default collation ignores case, so searches have always matched regardless of how a name was typed — and in PostgreSQL they do not, which turns a working lookup into one that silently returns nothing.
Why this comes up
The problem
Customer searches stopped matching after the move, because comparisons are no longer case-insensitive.
What you get
What we deliver
- Collation behaviour addressed explicitly, since comparisons change meaning
- Case-insensitive lookups reimplemented where the application relied on them
- Stored procedures and functions converted from T-SQL rather than assumed portable
- SSIS packages and SSRS reports given destinations, as neither transfers
- Identity columns mapped to sequences with their current values preserved
- Windows authentication replaced, because PostgreSQL handles identity differently

SQL Server to PostgreSQL Migration in Cambridge — common questions
- Why does collation cause so much trouble?
- Because it changes results rather than raising errors. Queries that matched a surname regardless of capitalisation stop matching, and joins on text columns can quietly return fewer rows — which is far harder to spot than a failure that announces itself.
- How is case-insensitivity restored?
- Deliberately, per column or query. Options include a case-insensitive collation, normalising values on the way in, or indexing a lower-case expression — each has consequences for indexing and performance, so it is a decision rather than a setting to copy across.
- What happens to SSIS and SSRS?
- They need replacing, and this is routinely omitted from scope. Integration packages and reports built on the Microsoft data platform have no PostgreSQL equivalent, so the migration is of the surrounding estate as much as of the database itself.
- Is the licensing saving the main driver?
- Often, and it can be considerable at scale given per-core pricing. It is worth setting against the conversion cost including the reporting and integration work, because organisations comparing licence fees alone tend to underestimate the project by a wide margin.
- Do you work with businesses across Cambridgeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including Cambridge and the surrounding Cambridgeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cambridge businesses do you usually work with?
- Deep-tech and biotech clients bring genuinely technical briefs, often involving data pipelines, instrumentation or research tooling. Beyond that we work across Technology, Life Sciences, Research, Higher Education and Biotech.
- Do you cover the areas around Cambridge?
- Yes — we work throughout East of England, including Norwich, Milton Keynes, London, Northampton. Cambridge is an urban area of roughly 150,000+, and we take on work across the wider Cambridgeshire region rather than the city boundary alone.
