I am trying to copy over chain data from one machine to another. Is there a way in the GUI to do this? Is there a how to/best practice for putting 300+ GB of chain data on new machine and launching ethereum wallet successfully? Do I launch ethereum wallet first then move chain data into file created? What would be proper steps to do this? I have tried but gotten 'can not connect to node' error


You need to move the chain file first. Then you start your wallet. It will see that you already have a chain and start from there.

  • Okay, so create file structure and only have chain data without 'current', 'lock', 'log' etc. etc? – Ethone Nov 28 '17 at 21:03
  • That did not work, still getting can not connect to node... – Ethone Nov 30 '17 at 20:29

Find your keystore file, its a json formatted file.

Install Mist on the other machine, find the location where geth is installed startup geth 1st using the --light or --fast parameters.

Move the keystore file over to the same location on the machine.
