How do I get new Z-cash address on launch day?

I am using OCMiner’s Nicehash miner, set up through the mining pool, currently with the test address. How do I obtain a new “real” address on launch day tomorrow? Secondly, once I obtain the new address, do I simply need to plug it into the new command script where the test address was, and update the address in the payout line on supernova? Sorry if this is a silly post, and thanks for the help.
