Sun International’s move from Adobe AEM to Umbraco shows why governance, marketing autonomy and sound discovery matter as much as the platform itself.
A CMS migration may begin with a technology decision, but its consequences extend across the business. Websites now underpin customer acquisition, loyalty, ecommerce, service and search. Changing the platform therefore changes how marketing publishes, how teams govern content and how quickly customer experiences can evolve.
Sun International’s migration from Adobe AEM to Umbraco is a useful reference point. Rather than treating replatforming as a like-for-like replacement, the migration became an opportunity to simplify a complex digital estate, improve content operations and build a more maintainable foundation. Its broader lesson is clear: migration succeeds when marketing, customer experience and technology leaders shape the outcome together.
When a platform decision becomes a business decision
A migration that improves technical flexibility but leaves marketers waiting on developers to publish is not a complete success. Nor is a marketing-friendly platform that creates new security, integration or governance risks. The real test is whether the new environment improves day-to-day delivery without weakening enterprise control.
That balance matters even more as organisations experiment with AI-assisted authoring, personalisation and search. These capabilities depend on structured, governed and reusable content. A new CMS cannot compensate for weak content foundations; it can only expose them faster.
As Matt Edwards, head of product at Bluegrass Digital, puts it: “The platform choice matters, but the operating model matters more. A migration should leave the business with clearer governance, more control and a digital foundation that can evolve without recreating the same constraints.”
The most valuable work happens before content moves
Experienced migration teams start by understanding the digital environment as it really operates: content models, integrations, templates, customer journeys, governance rules and hidden dependencies. The aim is not to transfer everything. It is to decide what deserves to be preserved, what should be rebuilt and what can be retired.
That discovery-led approach shaped Sun International’s migration. Bluegrass Digital began by assessing the existing implementation and the complexity surrounding it before defining the future platform. This created room to simplify rather than reproduce years of accumulated technical and operational friction.
What changed for Sun International
The resulting architecture uses Umbraco Cloud for the content layer and a Next.js frontend hosted on Azure for the customer-facing experience. It supports a digital estate spanning hospitality, gaming, entertainment, loyalty and self-service journeys. More importantly, it gives marketing teams greater day-to-day autonomy within the governance expected of a large enterprise.
The distinction matters. A migration should not be judged only by whether the new platform launches. It should be judged by what the organisation can do afterwards: publish faster, adapt customer journeys more easily and maintain control without creating unnecessary friction.
What to look for in a CMS migration partner
Platform certification is useful, but it is not proof of migration capability. Organisations should look for evidence of discovery audits, content modelling, SEO protection, integration delivery, cloud deployment, testing and post-launch support across complex environments. These disciplines reveal whether a partner can manage business continuity as well as technical implementation.
A CMS migration is a strategic reset, not a software swap
Sun International’s move from Adobe AEM to Umbraco shows what becomes possible when replatforming is treated as a strategic reset rather than a software swap. Bluegrass Digital’s work on the migration combined Umbraco expertise with migration discovery, architecture and delivery, demonstrating how technical decisions can support stronger governance and greater marketing autonomy.
For marketing and technology leaders, the question is therefore not simply which CMS to choose. It is whether the migration will remove old constraints or carry them into a new platform. The answer depends on the decisions made before content moves, and on choosing a partner that has done this work before.
