We have a stack of N4064F and N2000 series stacks that I need to update. I'm quite confused on the process to update the CPLD in stacked configuration. The first documentation I found from Dell stated the instructions are included in the downloaded file for a given update, however this isn't accurate I've found. I did find this community post:POST 

Dell support said to use this command:

update bootcode
reload

When I asked about what to do in a stacked configuration, I was told:

With the stack, it will be likely different. You will use a different command for it. Run the command "update cpld", ​and we do the Master the last. ​"update cpld x"​where x is the unit number ​and it will reboot that unit when done.

I'm confused about the expected behavior when updating each member. If I update the master last, will another member take over as master? I'm really confused on the whole process. If anyone could shed some light it would be most helpful.
