While merging two stacks Stack A and Stack B and you want Stack A to take over the entire stack, it is always recommened to reset the other stack configuration.  On Stack B execute  "restore factory_default stacking"  and then add the Serial number of these member to Stack A.

In a two-member stack with split-detection enabled, both the members of the stack remain active.
