The challenge

A high-end currency exchange company based in Canary Wharf, London, running a platform that allows users cheap bank-to-bank payments in foreign currencies.

The client maintained five separate legacy CMS websites that needed consolidating. Information sat across five databases with over 2,500 pages between them, each site carrying a different theme, with content in multiple languages. Customer login and navigation needed streamlining as part of the move.

Our approach

All five databases and themes were integrated into a single multisite platform, centralising customer information and simplifying the user experience.

The migration was planned around what had to survive it: content in every language, every existing URL, and the editorial structure the client’s team already understood.

Technical implementation

  • Five websites combined into a single multisite platform.
  • Over 2,500 pages and posts migrated with content intact.
  • Five databases consolidated into one source of truth.
  • Five themes reduced to a single maintainable theme.
  • Multiple languages supported throughout.
  • Redirects mapped so legacy URLs retained their search position.

The bulk of the risk in a migration of this size is not moving the data — it is proving nothing was lost. Every page was reconciled against the source before go-live.

The outcome

One platform to maintainFive codebases became one.
Nothing lost in searchEvery legacy URL redirects to its new home.
Simpler for customersA single login and navigation across all markets.

What we learned

Consolidating five themes into one was more valuable to the client than the database work. Their team now makes a change once instead of five times.
