Modernising your CMS – without a ‘big bang’ and without flying blind
Jörg Nölke
Evolving CMS landscapes hinder digital innovation. Complex integrations, historical dependencies and rigid platform structures make any change a labourious process.
But a CMS migration does not have to be a risky, complete overhaul.
Our guidebook shows how organisations can systematically analyse their existing CMS landscape, develop a future-proof composable architecture and manage the transition in controlled steps.

CMS migration is more than just a technology change
Many organisations face the challenge of modernising their content management systems, which have evolved over time. This is no longer simply a matter of replacing an old CMS with a new platform.
Websites, customer portals, apps and other digital touchpoints require consistent content, flexible integrations and increasingly independent development cycles. Monolithic CMS architectures can often only meet these requirements at considerable cost.
A modern CMS migration therefore begins even before the system is selected: with the digital requirements, the information architecture, the integrations and the organisational responsibilities.
The aim is not simply a new CMS, but a digital architecture that can be developed step by step.
From monolithic CMSs to composable architecture
A composable architecture combines clearly defined, reusable building blocks to create a variety of digital experiences.
Content, digital assets, APIs and workflows can be combined in a targeted manner without tying all functions and target audiences to a single central platform.
This does not necessarily mean introducing more systems. Rather, the key factor is which functions should be shared and where a deliberate separation makes sense.
This gives rise to three key principles for CMS migration:
Architecture before technology: Define target audiences, platform boundaries and responsibilities before selecting products.
Gradual migration: Migrate individual areas under real-world conditions, validate them and then scale them up.
Reusable content: Model content in a structured way so that it can be used across websites, portals, apps and other channels.
A pragmatic roadmap for CMS migration
A successful migration begins with transparency regarding the existing system landscape.
Which content and functions are actually being used? Which integrations are business-critical? Which bespoke solutions can be dispensed with? And which components should be operated independently of one another in future?
This transforms a high-risk, all-encompassing project into a series of manageable, verifiable decisions.
Excerpt from the Guidebook: a pragmatic migration roadmap
On this basis, a phased migration strategy can be developed:
1. Define scope and target vision:
Clarify target audiences, platform boundaries and architecture principles.
2. Analyse the legacy landscape:
Capture content, functionality, integrations and operational dependencies.
3. Make migration decisions:
Retain, migrate, redesign or decommission existing components.
4. Implement the first migration slice:
Validate a representative end-to-end area under real-world conditions.
5. Migrate in waves:
Move further areas to the new architecture in a controlled way.
6. Decommission the legacy system:
Resolve remaining dependencies and end parallel operation.
Frequently asked questions about CMS migration
What is a CMS migration?
A CMS migration refers to the transfer of content, functions and, where applicable, integrations from an existing content management system to a new platform or architecture. It may also involve the redesign of content models, workflows and organisational responsibilities.
Does an existing CMS have to be completely replaced?
Not necessarily. A phased migration allows individual functions and content to be transferred in a controlled manner. Existing components can continue to be operated temporarily whilst new architectural building blocks go live.
What are the benefits of a composable architecture?
A composable architecture enables digital functions and content to be combined in a modular way. This allows organisations to serve different digital touchpoints in a more targeted manner, reuse content and develop individual components more independently.
What should be clarified before a CMS migration?
Before starting, companies should analyse their target audiences, existing content, integrations, technical dependencies and organisational responsibilities. Equally important are a clear vision of the end state, a suitable first migration step and a plan for phasing out the legacy system.
