Hi guys,

I set up my full node and now want to move wallet from blockchain.info to my bitcoin-qt.

Blockchain.info is only providing the 12 words seed. I found a couple of guides about using Mnemonic code converter to extract BIP32 extended private key and how to generate it, which I did and got the long string starting with "xprv"
.
But the bitcoin-qt is not accepting this generated "BIP32 extended private key" and gives an error:

"Invalid private key encoding (code -5)."

Any idea?

Thanks
