@anotherlateminer on the new wallet update, will work the 'old' wallet.dat or is it with importing priv keys for each address how in Blackcoins Lore wallet?
It should work, but I'd suggest to create new wallet.dat with Core wallet (it will be HD by default) and send all your coins to it.
It definitely works. I did however let it create a new wallet and then imported my stake addresses privkey.
I would also suggest that with the new dopecore that folks use the dumpwallet command and save a copy of their master privkey. You can't import this master key into a wallet as of yet but you would be able to use the available tools found round the web to recreate your addresses and privkeys if the need ever arose.
