@aleksej996: Thanks. I guess that after Bitcoin Core is synced with the latest Blockchain, we cannot copy over the data directory folder to Bitcoin Cash wallet?

And I think this might be because Bitcoin Cash shares the same version of Blockchain with Bitcoin Core up until the time of hard fork. So, if the blockchain is already synced with latest version of Bitcoin then we cannot re-use it with Bitcoin Cash wallet.

So, looks like I really need to sync the complete Bitcoin Cash wallet once again. But it should be worth it
