Oracle to PostgreSQL Migration in Wrexham

Moving Wrexham organisations from Oracle to PostgreSQL, where the tables are the smallest part of the job. Decades of business rules live in PL/SQL packages, triggers and procedures that no automated tool converts reliably — so the estate to migrate is the code inside the database rather than the data in it.

Why this comes up

The problem

Core business logic sits in PL/SQL packages nobody has read since the people who wrote them left.

What you get

What we deliver

  • Database-resident code inventoried, since this determines the real scope
  • Each procedure assessed for whether it is still called before being converted
  • Logic converted or moved into the application, depending on where it belongs
  • Type and sequence differences handled, as these appear throughout the schema
  • Behaviour verified against the existing system rather than assumed equivalent
  • Licensing savings weighed against the conversion effort honestly

Oracle to PostgreSQL Migration in Wrexham — common questions

Why is PL/SQL the largest cost?
Because it holds the business rules. Packages and triggers accumulated over decades encode how the organisation actually works, often undocumented, and converting them means understanding each one first — which is analysis rather than translation.
Do conversion tools help?
With the straightforward portion, yes. They handle schema and simple procedures reasonably, and then leave the complex cases — precisely the ones carrying the important logic — which is where the effort concentrates regardless of what tooling is used.
Should logic stay in the database?
It is worth asking during the migration. Some belongs there and some ended up there because that was the convention at the time, and moving the latter into the application makes it testable and visible rather than hidden inside a system few people can inspect.
Is the licensing saving worth it?
Frequently substantial, and worth modelling against the full conversion cost. Oracle licensing is a significant recurring expense, but a migration involving hundreds of procedures is a multi-year programme for some estates — so the payback period is the number that matters rather than the annual figure.

Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Wrexham and the surrounding Wrexham area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
