Not exactly.
Excerpt from this article:
You could choose where you wanted to clone based on if you activated your character in Era or TBCC. You cloned to the other if you wanted to play the character in both. If you made no choice, your character was moved on in progression to TBCC (and now Wrath).
Sorry about the issue with some of the servers being locked in error in Era, Baklar.
Blizzard did address this in a different topic.
