Breaking stack Dell PCM6348

I have two dell Powerconnect M6384 configured as a stack. I need to get rid of stack and make both the switches as stand alone. As per the configuration, i see these were configured in such a way that one port was used from each switch and then configured as a port channel. So i have a few questions as i am not much aware how dell switches would behave. I know Cisco way of breaking the stacks.

Steps i need to do:

1. Move any standalone ports configured on the switch-2 to the switch-1.
2. Remove the switch from stack and associate configuration

switch-1(config)#stack
switch-1(config-stack)#
switch-1(config-stack)#no member 2

3. Disbale the ports used for stack.
4. Configure a management IP on the switch-2
5. After having access to the switch renumber the ports

switch-2(config)#switch 2 renumber 1

Questions:
1. When the stack is broken would switch-2 lose all the configuration it previously copied from the master switch-1? Or would it still have the configuration?

2. Would the port association in the port-channel configuration be automatically removed once we break the stack? Would switch-2 ports go away after breaking stack?

3. Should this be done out of business hour to have the minimum outage?

Would appreciate any suggestion on this.
