I am planning to upgrade my miners from 1.7.x to 1.8.x.
For testing purposes, I've made a copy of geth's data and then I run a new version of the geth miner against my copied data. After the new miner finishes DAG generation, I waited to see the Hashrate of the new miner. Unfortunately, the new miner hashrate is always zero.
Did I do something wrong?
