We have a couple of MDS9120's and a SUP1 9509 in our fabric that we want to retire. I'm pretty sure that I don't want to just shut down these switches, unplug the cables and call it good. Also the 9509 is the principal for two of our larger VSAN's and one of the 9120's is a principal for another that we are still using. Also, this same used to have an IVR zoneset which I think is gone, at least I don't see it when I look at IVR. Current all the switches in the fabric are running 3.31c code. Since we are planning moving to the 4.x we want remove these since they will not be supported.
So, what is the procedure to make another switch the principal of a VSAN, and once a switch is no longer a principal what is the procedure for cleanly removing it from the fabric? If someone has some insights or can point to me to documentation that covers this, it would be greatly appreciated.
