I don't have enough time and speed to be able to download whole Bitcoin chain which is approximately of 175 GB. I have transferred my Bitcoins to Electrum wallet and have written down my Private Keys. I hope as of alternative I have done good and it should be fine to avoid any complication. Any thoughts of this would be appreciated.
I hooked the ABC wallet to a copy of the core blockchain - seemed to work fine. You may want to delete the wallet.dat and peers files on the copy before you start up.
