I'd like move my bitcoin cash wallet from one server to the other using the cli.

Server 1: bitcoin abc: 0.17.2. Server 2: bitcoin abc: 0.18.0

I have done the following:

  1. ran the command: backupwwallet "myfile.dat" on server 1 successfully.
  2. copy the "myfile.dat" to server 2.
  3. rand the command: importwallet "myfile.dat".

I get the following the error when trying to import the wallet:

error code: -8
error message:
Cannot open wallet dump file.

I have also tried to replace stop the node on server 2 and copy the wallet.dat over to the other server and then start the wallet up again on server 2. I get the following error in the logs:

CDBEnv::Open: LogDir=/home/cryptodaemon/.bitcoincash/database ErrorFile=/home/cryptodaemon/.bitcoincash/db.log
2018-09-09 07:48:21 Failed to rename wallet.dat to wallet.dat.1536479301.bak

How can I move the wallet from one server to another? Could anyone give me pointers in doing this?

importwallet is the opposite RPC of dumpwallet, not backupwallet.

backupwallet creates a copy of your wallet.dat file. You restore that file by putting it back in the data directory.

dumpwallet creates a wallet dump (just private keys, no history, addresses, labels, accounts, ...), which can be imported into an existing wallet using importwallet.

Probably this is Bitcoin ABC's bug. As an alternative to backupwallet, dumpwallet might work.

In addition, please file a bug report at https://github.com/Bitcoin-ABC/bitcoin-abc/issues.

Check which database version the various abc -qt wallets use as their backend. Any change will prevent using the old one from writing a wallet.dat suitable for the new one. To do what you are doing, I'm on step 2 of - create an account at a reputable exchange - do a small test transaction to check that your coin gets there - do another small test transaction to check that you can get coin back to your new wallet - move your coin from home to the exchange - move your coin from the exchange to your new wallet at home That is four transaction fees just because someone thought that bdb4.8 was too samey to keep the same.
