SQL Server to PostgreSQL Migration · Coventry
SQL Server to PostgreSQL Migration in Coventry
Moving Coventry 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

Working in Coventry
West Midlands
Coventry's automotive and mobility research base means a lot of local firms sit in complex supply chains, where the useful software is usually the piece that connects systems nobody planned to connect.
Supply chain integration dominates — connecting order, quality and delivery data between manufacturers and the tiers above and below them.

SQL Server to PostgreSQL Migration in Coventry — 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 West Midlands?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout West Midlands, including Coventry and the surrounding West Midlands area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Coventry businesses do you usually work with?
- Supply chain integration dominates — connecting order, quality and delivery data between manufacturers and the tiers above and below them. Beyond that we work across Automotive, Advanced Manufacturing, Higher Education, Logistics and Gaming.
- Do you cover the areas around Coventry?
- Yes — we work throughout West Midlands, including Birmingham, Leicester, Northampton, Wolverhampton. Coventry is an urban area of roughly 370,000+, and we take on work across the wider West Midlands region rather than the city boundary alone.
