# **CMS Case Study: Emergency migration for a leading media group**

How a modern CMS migration enabled Arena Media to replace a deprecated legacy platform, stabilise eight publications, secure subscriptions and payments, and retire its outdated system all under extreme time pressure.

## **How Arena Media kept 8 publications online during a critical CMS transition**

Arena Media had only a few months left to move away from a fully deprecated CMS with no exit path for authentication, subscriptions, or payments.  
After six months of stalled progress, We took over the project and led a full migration to Arc XP launching eight sites in just four weeks, normalising over 1,000 subscription variations, and ensuring zero downtime throughout the transition.

### What you’ll learn in this case study: 

- - Why Arena Media urgently needed to replace its deprecated CMS (Cosmos).
    - How code.store executed eight website launches in four weeks without disrupting publishing.
    - How identity, subscriptions, and two South African payment gateways were migrated under extreme time constraints.
    - How Arc XP’s platform (Page Builder + Subscriptions amongs other features) became the foundation of a sustainable CMS stack.
    - The measurable outcomes: zero downtime, a unified subscription catalogue, and a full retirement of Cosmos.
