ICX6450 Stacking Question

Hello, I have 6 ICX 6450 in a stack. 3 on one floor and 3 on another floor. We’re no longer leasing 1 of the floors and therefore consolidating everything. The 3 switches that need to be moved are acting as the active and standby switches with all others being members. What would be the best way to move these switches?Should I make one of the switches NOT being moved the active switch and reload the stack before unplugging those switches to be moved? Or can I just unplug them and move them without doing anything? Not sure what happens to the stack when it loses both active and standby switches.Any help will be greatly appreciated.
