Newbie running full node (Bitcoin Core): Commands to import wallet with passphrase from external USB stick? And how to sweep paper wallet?

Question

I need help with:

• Which console commands (Linux) to use to import external USB stick wallet (with passphrase) created by an earlier version of (Linux) Bitcoin Core?

• How to sweep paper wallet (with passphrase)?

For the first time, I want to transfer from a Bitcoin Core wallet to an exchange to sell.

Answer 1

At the /home/user/.bitcoin directory, replace the wallet name directory with the one to copy.

Make a burner wallet to get some understanding, then replace the burner wallet with the one you want.
