I've everything running fine on old laptop with Monero v 0.11.0. Now I try to move this (Monero GUI Folder, blockchain folder and Keys) to new laptop. And try to restore from keys, I can see it is showing my balance correctly. Now while starting Daemon with fails and I try to do it from cmd line and it fails

May be something corrupted. What is right way to Move Wallet with blockchain db file to new laptop?

  • try adding --drop-txpool to your command line options – Joss Bird Feb 28 '18 at 17:58

Before copying over the files of the Monero blockchain, make sure the daemon is no longer running. Perform a monerod exit from a Command Prompt if necessary.

Then, you should copy over the entire directory, in your case E:\MoneroBlockchain to the target computer. On the target computer, I would just remove those .bin files, before starting the daemon. This way, the daemon will rediscover th proper state.

Note: Monero 0.11.0 isn't the lastest version, you should probably use on the target machine.

The wallet files can just be copied as is. This should work the same on the target computer, but again, try to use the latest version of the software. And always keep a copy of your mnemonic away from the computer. That guarantees you'll always be able to recover your funds.
