I have a Brocade fabric consisting of a 48K as the core, DCX as the edge, 5100 and 5000 as the edge switches. There is a similar redundant fabric in place. We are in the process of promoting DCX as the core and isolate the 48K from the fabric, since all its connections except the ISL's have been moved over to the DCX. Here is the plan that I have prepared:
Steps to be done prior the change window:
Steps to be done at the time of change window: (One Fabric at a time)
Please let me know if I have missed anything.

If the 48K is the principal switch and you are isolating it from the rest, you don't need to force a BF, it will be automatically done when you remove the last ISL to the 48K. You can set the DCX set to be the principal with fabricprincipal command and it will become when the BF is performed.
