Question about changing switch stack# in a production environment with already configured ports.

We installed a new stack at one of our locations. The stack from top to bottom is going 1, 3, 2, 4. We had no knowledge of this until later on when we already have configuration on the ports for switch 3 and 2 (Traced MAC addresses to find the ports, you know the drill, etc.) ((We are remote)).

The question is, when we change switch 2 to switch 3 and switch 3 to switch 2, will the config for each switch hold on to the number? Or change with each switch?

Example: 2/0/35 is currently configured with switchport access VLAN 10, when we swap switch 2 so that it is now switch 3 will the configuration now have 3/0/35 on VL10? Or will it stay 2/0/35 on VL10?

Any help is greatly appreciated.

Edit; Switches are Cisco Catalyst 2960X-48FPS-L
