In May 2024 we examined 72,000 legacy subscription entitlements before migration to a common service. Sixty-six thousand mapped to an explicit current meaning. Six thousand needed commercial interpretation: four thousand concerned earlier bundles and two thousand related to complimentary arrangements. A successful account match could not explain which publication or period each entry represented. The proposed migration rules risked making that unresolved meaning look settled simply because the destination required a valid product code.
The platform sponsor preferred a standard mapping followed by corrections through ordinary support. Subscriber services objected that readers would bear the uncertainty when they tried to use what they had bought. I backed an eight-week programme costing AUD1.8 million to examine the disputed entitlements with their commercial owners. We preserved existing access under agreed commercial authority while the interpretation continued, rather than invent a new entitlement or remove one merely to make the conversion simpler.
Four thousand five hundred of the six thousand entries acquired a confirmed mapping. The remaining 1,500 kept an assisted route and an explicit owner for the unresolved question. Our final migration account therefore showed 70,500 mapped entitlements and 1,500 exceptions in that cohort. It did not describe 72,000 distinct people, because a reader could hold more than one subscription. Nor did the exercise establish a retention improvement, new revenue or the correctness of every entitlement outside the examined group.
The choice kept a less convenient service arrangement alive and used time the sponsor had wanted to devote to new features. It also prevented the new platform from becoming the apparent authority for a promise the business had never interpreted. I wanted the system to carry the commercial decision, including its uncertainty, rather than let the database's need for a complete field become the reason that decision was made. The remaining assisted work was part of the delivery account, with responsibility retained until a defensible explanation could replace it.
I would bring commercial interpreters into the entitlement inventory before setting the conversion scope, so older bundles receive an agreed decision route before the migration timetable hardens.
