You don’t understand how it works. Blizzard is copying your toons to both servers. All you do is pick which era you want to play. You aren’t transferring or anything.
Again you’re not copying. Read my post that has ALL the clone information. Blizzard is not touching your gold. You need to read the post so you understand how it works.
“Gold is included in inventory. When you activate your vanilla clone it will have the same amount of gold you had on may 18th. They are not capping gold.”
