Migrate a 3-stage CLOS fabric to 5-stage CLOS fabric
Usage:
  efa fabric migrate [flags]
Flags:
   --type string                                  Type of migration [3-to-5-stage] (default "3-to-5-stage")
   --source-fabric string                         Name of the 3-stage CLOS fabric to be migrated
   --destination-3-stage-leaf-spine-pod string    Name of the 3-stage POD into which the leaf and spine devices (of the 3-stage CLOS fabric) 
                                                  need to be moved during migrate
   --destination-3-stage-border-leaf-pod string   Name of the 3-stage POD into which the border-leaf devices (of the 3-stage CLOS fabric) 
                                                  need to be moved during migrate
   --super-spine-asn-block string                 ASN block to be used by the super-spine devices of the migrated 5-stage CLOS fabric
   --super-spine-peer-group string                Peer Group to be used by the spine devices of the migrated 5-stage CLOS fabric
  1. No or least traffic loss.
  2. The command supports migration of a single fabric from 3-stage to 5-stage and not merging of multiple 3-stage Clos fabrics into a single 5-stage fabric.
  3. If border-leaf is present / not-present in the fabric, then you must / must not provide the destination-border-leaf-pod.
  4. If the border-leaf is connected to the spine devices in an existing 3-stage Clos fabric and you want the border-leaf to be connected to the spine even in the migrated 5-stage Clos fabric, the migration allows this.. Provide the same pod name for both the destination-3-stage-leaf-spine-pod and destination-3-stage-border-leaf-pod.
  5. Migration is supported with multiple single-homed, multiple multi-homed border-leaf devices.
