Unified reporting: prepare for the 31 December migration

What changed

Inventory the saved reports, schedules and recipients your business depends on. Reconcile familiar metrics in the new reporting experience before the old pages disappear. Do not assume a promised migration tool has already handled everything: verify the current options and test the resulting deliveries.

What this update covers

This article records the Retail Media update published in Paid Media News Week 38. The cited evidence is source-supported. It supports the specific scope described above; it does not establish a broader rollout, eligibility, performance outcome or commercial result beyond that evidence. The primary material for this record is Amazon announcement.

How to assess it in your account

Start with the linked source and check whether the stated product, geography, account type and access conditions match your own setup. Treat an announcement, a limited beta, an account observation and a useful reference differently: each may be valuable, but they carry different levels of availability and certainty. If the change is relevant, document the current workflow before making a change so that later results have a meaningful baseline.

For “Unified reporting: prepare for the 31 December migration”, define the decision you need to make before treating it as an optimisation opportunity. That could be whether the capability is available, which customer journey it affects, what data is required, or how it interacts with an existing campaign, feed, creative process or measurement setup. Use a bounded test or review where access allows, and keep the source, date and account conditions with your notes.

Practical next step

Review the implementation details in the original material, then agree one success measure and one guardrail before acting. Compare the result with your existing setup rather than relying on a product label, a screenshot or a reported example alone. If access is selective or the source describes an observation, retain that limitation in any internal recommendation. The source media attached to this article was selected for the same update and is credited below; it illustrates the reported development but does not replace the underlying source documentation.
