No miner change required, the pools are gonna do the job for you

please bear in mind that by now, the only pools that are supporting the hard fork are :

LOUDMining.com
MiningOcean.org
uplexa.miner.rocks
uplexa.herominers.com
upx.ms-pool.net.ua

If you want to mine to another pool, please take your responsibility and contact the pool owner directly to ask him if he supports the fork
