Delete them, save the costume etc.
You'll be able to make them exactly the same on Union assuming the character name isn't taken, there's no real reason to pay transfer fees when it's only about 30 mins work including costume design for each one (I tend to spend upwards of 20mins to an hour in character creation)
By "Main server" I assume you mean what comes up as the top of the 4 on the selection screen, and that's simply whatever server you last selected.
Thanks. I wasn't sure exactly how the transfers work. I've never done. Level 5 is not that high but that is 5 hours of work for each of my characters which adds up to 15 hours. I'm paying the fee.
I'm have some low level characters(3 characters at level 5) on the Defiant that I want to move to Union.
I'm considering two options:
1. Delete them and recreate them on Union
2. Pay the transfer fees from Defiant to Union.
I have these questions:
1. How long does it take to transfer?
2. If I delete all of my characters, will I be able to choose Union instead of Defiant as my main server?
Over the holiday weekend, I thought it would be cool to be on Defiant but they have low volume(1 green dot all of December and January so far). Union gets two yellow dots which is manageable to me. I'm hoping to get this resolved before the double xp weekend.
