Our team has planned and executed data-centre decommissioning programs using replacement infrastructure, DNS traffic control, failover testing, rollback planning, and coordinated migration of applications and services.

Project challenge

Retire a production data centre while preserving external connectivity, remote access, application availability, and the ability to reverse changes during migration.

Delivery

  • The team built and activated a replacement site with replicated infrastructure, services, and secure connectivity.
  • The team used DNS health checking and traffic redirection to move services between sites in a controlled manner.
  • The team performed failover simulations, TTL optimization, secure-access validation, and rollback rehearsals.
  • The team documented migration steps, cable/port mappings, stakeholder dependencies, and final decommissioning activities.

Outcome

Legacy infrastructure was retired through a phased migration model designed around continuity, validation, and rollback rather than a single high-risk event.
