You are approaching the end of your lease for older redundant Brocade fabrics and want to
migrate to newer Brocade 16 Gbps switches. What are two ways to do this with minimum
disruption to the existing fabrics? (Choose two.)

A.
Install the new switches, merge them into the existing fabric using new cables, and move the
device connections one at a time to the new switches.

B.
Configure the persistent domain ID on the new switch and set it to the same domain ID of the
switch being decommissioned, then attach it to the existing fabric.

C.
Create a completely new redundant fabric using Brocade 16 Gbps switches and migrate device
connections one at a time to the newer fabric.

D.
Downgrade the firmware on the decommissioned switch before adding the new switch and
removing it from the old switch of the fabric.
