1. If I want to replace one switch in the stack (slave switch) in a stack of 4 switches, with a spare do I have to first upgrade my spare 3750 to the same IOS as the other members in the stack or will the current stack master automatically copy the IOS from itself to the new replaced switch.
2.If the answer is that the current stack master will automatically copy the IOS from itself to the new replaced spare, then is the answer the same whether the new spare is a higher or lower version of IOS than the current master. Or will I get a version mismatch error under some circumstances.
3. Lastly will the config get automatically copied from the master to the new spare.
I have read information at the following links
but reading is not the same as asking for the input of someone who has done this practically.
In some of this forum entries it says to copy the IOS first into the spare switch and also to copy the template into the spare switch. What template is it talking about.
