Migrating to Cisco ACI is a major milestone for any data center. But without a clear ACI migration strategy, it can quickly become complex.
In this video-based article, I explore a high-level roadmap for moving to ACI, compare Greenfield and Brownfield approaches, and help you decide between a Network-Centric and Application-Centric design. This is the foundation of a successful migration playbook.
Summary
- ACI Migration is moving workloads, policies, and connectivity from a legacy network to the ACI fabric.
- In Greenfield ACI deployment, we build a new data center fabric with no dependency on an existing network.
- In Brownfield ACI deployment, we move an existing active data center to the ACI fabric.
- In most migrations, the ‘Network-Centric’ approach is the safest way to quickly bring your workloads onto the ACI fabric. You can always optimize for ‘Application-Centric’ features once the migration risk is gone.

Hey Salman,
It was a nice video on the legacy to fabric migration thanks for this.Please can you also post a video of how to migrate from existing fabric to new fabric.
Hi Sandeep,
Do you mean from existing ACI fabric to a new ACI fabric?
