Want to go back to my old realm

I saw a topic about this so sorry in advance , but i couldn’t find it.

Last night i transfered my character to another realm( i wanted to) but to the one i wanted , because i thought it was bugged and showed only 1 realm to move to. Later i read that there are only specific realms you can transfer to.
The realm is Low Pop and sometimes its hard to get things done.

Can i go back to my old realm where i played since the beggining and i have 2 other characters there and how ?
I have no problem if there is a paying option for this.

This is an irreversible one way move. CS cannot help you.

At the current moment there is no plans for any additions to paid services. Keep an eye out on the Classic forums for any news about this as CS will not have any updates until there’s an official blog or other news posted there either.
