Power BI Migration · Cardiff
Power BI Migration in Cardiff
Migrating Cardiff organisations onto Power BI from another reporting platform, where the model has to be rebuilt rather than converted. Every tool shapes data differently, so the useful question is not how to translate the old reports but which of them anyone still uses — and that answer is usually a fraction of the total.
Why this comes up
The problem
There are four hundred reports on the legacy platform and the migration plan assumes all of them are coming across.
What you get
What we deliver
- Usage measured on the existing platform, so migration effort follows real demand
- Reports triaged into rebuild, consolidate and retire
- The data model designed for Power BI rather than mirroring the old structure
- Calculations rewritten against the new model, since translation rarely works
- Users involved in verification, because they know when a figure looks wrong
- The old platform decommissioned once each area is signed off

Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

Power BI Migration in Cardiff — common questions
- Do we need to migrate every report?
- Almost certainly not. Usage data on the existing platform typically shows a large proportion opened rarely or never, and migrating those spends real effort reproducing something nobody will look at once it arrives.
- Can calculations be translated?
- Rarely cleanly. Expression languages differ in how they handle context and filtering, so a literal translation frequently produces something that returns the right number in one situation and the wrong one elsewhere — rebuilding against the new model is safer.
- Who should verify the results?
- The people who use the reports. Technical reconciliation confirms totals match; only the person who reads a report weekly notices that a category has been mapped plausibly and wrongly, and that class of error survives every check except theirs.
- When can the old platform be switched off?
- Area by area, as each is signed off. Keeping it available indefinitely means paying for both and gives people a reason not to adopt the new one, so a defined retirement date per area is what actually completes a migration.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
