I have a private blockchain where I'm testing a contract and I want to re-deploy a very-slightly modified version. I need to delete the old one first. I control all of the nodes, so I can do this.
But I don't know how?
I tried deleting the ~/.parity/chains config dapps directories, but the contract is still out there.
Do I have to delete these directories on every node? Do I have to delete the "network" directory also?
