SQL Server to PostgreSQL Migration · Milton Keynes

SQL Server to PostgreSQL Migration in Milton Keynes

Moving Milton Keynes 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 Milton Keynes — 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 Buckinghamshire?
Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Milton Keynes and the surrounding Buckinghamshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Milton Keynes businesses do you usually work with?
Internal tooling is the common request — head office teams needing systems that sit between enterprise platforms nobody wants to replace. Beyond that we work across Technology, Logistics, Financial Services, Retail and Automotive.
Do you cover the areas around Milton Keynes?
Yes — we work throughout South East, including Northampton, Oxford, Cambridge, London. Milton Keynes is an urban area of roughly 290,000+, and we take on work across the wider Buckinghamshire region rather than the city boundary alone.
