// ccm & migration practice
Modernising a legacy document platform without ever interrupting production.
Statements, renewal notices, contracts, invoices: a customer communication platform never stops. We migrate these platforms from the measurement of the estate through to the actual shutdown of the source platform, with proof of equivalence at every cutover.
// 01 · what we do
A platform in production for fifteen or twenty years carries anything from a few hundred to several thousand document templates. Scale changes the size of the programme, never its method.
A real inventory of templates, volumes produced over a rolling twelve months, dead templates, variants of the same document, business logic buried in the layouts. The study becomes a measurement, and the scope a figure.
Merge redundant templates before migrating, especially after mergers of entities, then set up shared document governance that prevents them drifting apart again. Migrating an estate that has not been cleaned up just moves the debt.
Analysis of the legacy sources, normalisation into a canonical model, tool-assisted generation for the target engine. Then automatic comparison of both chains’ output, document by document, against a definition of equivalence settled at the outset.
Parallel running and flow-by-flow cutover. Annual flows are validated outside peak periods, on test sets derived from the previous year’s data, within a controlled GDPR framework. Through to the shutdown of the source, not just letting it go dormant.
// 02 · why now
For twenty years, shutting down a document platform was desirable in theory and unfundable in practice: nobody could say what it contained, what rebuilding it would cost, or how to prove the new chain would produce the same documents. Four obstacles have fallen together:

Mass document production also raises the question of the accessibility of the documents it issues: this is where our document-production experience carries over directly, see our Accessibility practice.
