I have 1BTC in a MultiBit Classic 0.5.19 wallet and realizing how outdated its fee setup is I'm trying to move it to a newer wallet. I set up a Bitcoin Core wallet and let it sync and then tried to send .5btc to it on December 11 but it's still unconfirmed because the most fee the old wallet lets me send is .00005 per kb. Yesterday I tried the 'reset blockchain and transactions' as that's the only thing I can find built into MultiBit to try.
So my question is what is the best way for me to move out of this MultiBit Classic wallet into something modern? I still have .5btc in it and the other .5btc out there unconfirmed since Dec 11.
