[BitcoinException('invalid bitcoin address: LVhe3m3p8RqqWYagk3DXdmfJurLNQKbSU9')]

I have an outdated Electrum wallet (version 2.9.3.1) from which I want to transfer the amount to a new Electrum wallet.

I created a new wallet (legacy option) with the latest version of Electrum.

Opening the old wallet from within the new wallet triggers an error:

BitcoinException('invalid bitcoin address: LVhe3m3p8RqqWYagk3DXdmfJurLNQKbSU9')

Alternatively, transferring the total amount to a receiving addresses of the new wallet throws an error on the receiving address:

'Invalid lines found'



Any suggestions are welcome and appreciated.

Thanks in advance!
