Bitcoin Core – BCH in an existing BitcoinCore wallet? Would you like to use my September 2020 BitcoinABC chain? or?

What is the easiest way to get my BCH?

edit: I installed ABC on my second (Ubuntu) laptop. (Core and ABC conflict, so if you don’t have Jiu-Jitsu, you’ll need to be on a different computer.) I pointed the 2020.09 chain, put it in my Core wallet on 2017.12, and ran it. I scanned it again and found the balance without a problem.

But wait! I have XEC, which to me is eCash and not BCH! Therefore, BitcoinABC is now an eCash wallet.

Is there a full node BCH wallet that can point to an existing chain? (I still have the 2020.09 copy.)
