Replacing a Stack Master in a 3750 stack

We currently have as our stack master a 24 port Non-PoE that we want to replace with a 48 port Non-PoE. The 48 port switch at one time was provisioned as switch 3 in the stack (not the master). Correct me if I am wrong, but theoretically all I should need to do to get this working is to shut off the existing master so it re-elects a master and then provision the 48 port switch as the new switch one and make sure switch 1 has a high priority?

Do I need to write erase the switch that is replacing the current master first?

Replacing a Stack Master in a 3750 stack

Re: Replacing a Stack Master in a 3750 stack

Would I set this priority on the new master before connecting it with the stack wise cables?

I believe you can, but I don't recall just adding a new stack member causes a stack election (if you're trying to get the replaced switch to become the stack master).

Yes, you can configure priority on the new master before conencting.

Use command  : switch       priority <      new-priority-value>

Make sure you are giving a value which is higher than current master.
