Now that the details have been straightened out between former Black Desert Online Russian publisher GameNet and Pearl Abyss regarding game data, it appears that players can now begin the transfer process. According to a post on the brand new Black Desert Online site, the new version will be live starting November 22nd. Up to that time, players can apply to have their characters transferred.
All new and transferring players will receive a chest with armor and weapons, a Rank 8 horse and a special title. Those who transfer ahead of November 22nd will also receive a bonus gift with dye, a premium character class costume and a polar bear.
Players will need to complete the character transfer process before December 31, 2018 after which time it will be deleted.
