What Enterprise CMS Migrations Actually Look Like Behind the Scenes

Enterprise CMS migrations sound straightforward on paper. Move content from one platform to another. Launch the new site. Move on.

In reality, they are among the most complex programs large organizations attempt.

I saw this firsthand while supporting a national healthcare system migrating thousands of websites from legacy platforms into Adobe Experience Manager. What initially looked like a technology upgrade quickly revealed itself to be something much larger. It was an organizational transformation.

The Scale Is Harder to Grasp Than It Looks

Large organizations rarely operate a single website.

In healthcare alone you may find hospital sites, clinic pages, physician directories, patient education content, service line pages, and regional microsites. These often operate independently and sometimes run on completely different systems.

In one scope we reviewed, a single regional network had fourteen websites and roughly six thousand pages.

That was one region.

Multiply that across a national system, and the complexity compounds quickly.

Governance Is the Actual Hard Part

Technology is rarely where these programs get stuck.

Governance is.

A migration of this scale requires coordination across marketing, engineering, analytics, UX, external vendors, and regional stakeholders. Each group has its own priorities.

Without a clear structure to manage alignment, programs drift.

We created a cross-functional governance body called the Adobe Service Council. This group met regularly to align priorities, resolve conflicts, and manage backlog intake for the platform.

It was not glamorous work. But it was the operational backbone that kept the program moving.

Backlog Discipline Matters More Than Most Teams Expect

Large digital platforms generate a constant stream of requests.

Enhancements. SEO fixes and analytics needs. New components. Feature requests.

Without a structured intake process, those requests accumulate in a backlog that nobody owns.

We addressed this by implementing a structured Agile framework within Azure DevOps. Work was organized into epics, features, and user stories. Business requests were translated into backlog items engineering teams could execute.

Simple in concept. Difficult in practice.

Maintaining backlog discipline is often the difference between programs that deliver and programs that stall.

Multi-Vendor Coordination Adds Another Layer

Most enterprise migrations involve multiple consulting firms and development partners.

One team may manage platform architecture. Another may handle UX design. Another may own specific feature development.

Aligning these groups requires constant coordination.

Release planning, regression testing, and deployment sequencing all have to be managed carefully. A change that seems minor in isolation can create major disruption if it is not properly staged and communicated across teams.

Migration Is Also a Content Strategy Opportunity

A CMS migration is not just a technical exercise.

It is one of the few moments when an organization has attention and budget focused on its digital experience all at once.

During migration planning, we identified opportunities to consolidate duplicate pages, improve service line content, strengthen SEO, and introduce clearer calls to action.

Many organizations default to a "lift and shift" approach.

The smarter approach is to treat the migration as an opportunity to improve the experience rather than simply preserve it.

Program Management Is the Hidden Engine

From the outside, CMS migrations look like engineering projects.

Inside the program, they are coordination projects.

Someone has to align teams, track priorities, manage release schedules, monitor budgets, and ensure hundreds of small decisions move in the same direction.

That is the real work of digital transformation.

Technology enables the change. Governance makes it possible.

Where This Is All Heading

Organizations are revisiting these platforms now, and the complexity is increasing.

Modern digital ecosystems now include analytics platforms, customer data platforms, personalization engines, and AI-driven content workflows layered on top of the CMS foundation.

What used to be a website platform has become a digital operating system.

The organizations that navigate this well will treat these efforts as enterprise programs rather than simple website projects.
