How are you trying to do it?
(I hope you're not running both on the same computer, or you installed ABC in a different directory so it doesn't overwrite your wallet.dat file from bitcoin core)
thanks for your reply
i have tried that.
I have backuped the wallet.dat from bitcoin core before sending the remaining bitcoin to the ladger.
than i have deinstalled the bitcone core and installed the bitcoinabc.
i have waited for the bitcoin abc to synchronize with the network and
than i have copied the wallet.dat originated from the bitcoin core into the bitcoin abc directory.
i must say that when i copied the wallet.dat, the bitcoinabc was still 2 days behind the synchronization, might that be problematic?
now the bitcoin abc wallet shows the last transactions i made but it shows them as BCH actions and the total sum of the wallet is still 0.00000000
much appreciate the help!
