You cannot directly transfer a character from one server to a separate server.
If you start on a different server, you will have to use a new character.
However, if you wait, your server will probably be merged with some others, and this might mean that you get some new company from people of other servers. You will retain your character as it stands, but your server will join with the populations of other servers. You will become part of a new, larger server, where the community might act differently and where you might find some better company.
