Migrate from legacy CMS without operational disruption
Methodical transitions from AEM, Sitecore, and Kentico to modern, composable architectures. Zero-downtime launches. Total data integrity. For the world’s most demanding brands.
Strategic partner for high-scale brands
Migration built for continuity
Enterprise migration is a risk and operating model decision
Not a replatforming exercise. The teams that treat it as a technical lift-and-shift are the ones that end up with broken integrations, lost SEO authority, and an editorial team that never fully adopts the new system.
Our Legacy Exit approach is built around the operational reality of running a live enterprise, maintaining continuity throughout, and coming out the other side with a system that works better than what you had.
The modernization roadmap
A phased approach that balances technical execution with operational continuity
Each phase is sequenced to protect live business operations while building toward a governed, composable target state.
01 | Foundation
Inventory & audit
Identifying and eliminating redundant legacy content before the move, ensuring your new system is lean and high-performing from day one, not carrying years of accumulated debt into a new platform.
02 | Architecture
Structured schema mapping
Designing semantic schemas that treat content as data, allowing it to flow reliably to web, apps, IoT, and AI agents. This is what separates a migration from a genuine modernization.
03 | Continuity
Parallel-run strategy
A pragmatic migration methodology that maintains full business continuity and SEO authority during the transition, with no blackout windows, no performance drops, and no editorial team held hostage to a cutover date.
04 | Guardrails
Governance and workflow design
Tailored workspaces and Role-Based Access Control designed for global teams, so brand consistency is enforced by the system, not by a process document nobody reads.
The deliverables
What you walk away with
Every migration engagement produces a concrete set of outputs your team can act on immediately, not a report that gets filed away.
- Zero-downtime launch plan
- Clean, validated content ready for migration
- Structured schema and content model
- Integration dependency map
- Governance and workflow design
- Phased migration roadmap with go/no-go gates

Migration risks we mitigate
Enterprise migrations carry real commercial and operational risk
We identify and mitigate the risks that derail enterprise migrations before they become problems.
01
SEO performance risk
Parallel-run strategies, redirect governance, and monitoring frameworks protect organic authority and performance during cutover.
02
Editorial downtime risk
Staged releases and workspace alignment ensure content teams remain fully productive throughout, with no enforced freezes.
03
Data loss and quality risk
Schema validation, structured mapping, and reconciliation checkpoints protect content integrity from source extraction through to final cutover.
04
Integration breakage risk
Dependency mapping and contract testing prevent downstream system failures, with every connected system validated before go-live.
05
Compliance and governance drift
Role-based access control and defined publishing models ensure standards hold at scale, not just at launch.
Every risk above has a defined owner, a mitigation approach, and a checkpoint in our delivery model.
Nothing is left to assumption.
