Will the old server be deleted? Having two servers in parallel may confuse users. And one more question- when rewards will increase?
1) It will be deleted as soon as most of users will go over to the new server.
2) Current block reward is 1.3 P59 - 0.78 Masternode and 0.52 staking. It will increase after 36720th block and will be 1.4 P59 per block - 0.91/0.49 MN/staking.
