Migrate a 3-Stage Clos to 5-Stage Clos Fabric

When the 3-stage Clos fabric is migrated to a 5-stage Clos fabric,

  1. Fabric stage is changed from “3” to “5”.
  2. Fabric state is changed to “migrate-success” or “migrate-failed”.
  3. Leaf and Spine devices will get the POD name = destination-3-stage-leaf-spine-pod.
  4. Border Leaf devices will get the POD name = destination-3-stage-border-leaf-pod.
  5. App State of all the leaf, border leaf and spine devices will be changed to “cfg-refreshed”.
  6. Pending Configs of all the leaf, border leaf and spine devices will be changed to “BGP-C, BGP-D”.
Note

Note

Brownfield configuration is not supported on the new devices added to the fabric in "migrate-success" state.
