Good News! Blizzard has officially announced that Burning Crusade Classic will launch on June 1, with the Pre-Patch coming on May 18.
MmoGah, a professional WoW Classic gold seller, will share more details about TBC Classic's Character Selection, Character Cloning Service, and Level 58 Character Boost. Most of the content in this article is quoted from TBC Classic's official site.
Beginning with Pre-Patch day (May 18), you should make a choice on each of your existing Classic WoW characters whether to progress to Burning Crusade Classic or play on a Classic Era realm.
All current World of Warcraft Classic servers will progress to Burning Crusade Classic content as of the Pre-expansion Patch. When you first log in, you should make a choice on each existing character whether to advance that character to Burning Crusade Classic or choose to play on a WoW Classic Era realm available as a new game download on the Battle.net Desktop App.
If you last logged into WoW Classic before Pre-Patch day, your default option in the Battle.net Desktop App will be Burning Crusade Classic. If you want to move to WoW Classic, you should select that option.
When you select the "Play Burning Crusade" button, you will need to confirm your choice by typing in the character's name on the confirmation interface.
Once you click "Accept", your character will advance to Burning Crusade Classic. Although you can't play Outland before TBC releases, you are able to play Blood Elf & Draenei Races and learn the Jewelcrafting profession with early access.
If you want to play on Classic Era realms, you should select the World of Warcraft Classic game in the Battle.net Desktop App and install it as a new game.
Character Cloning Service
If you want to play a character in both worlds, you can choose the Character Cloning Service (available on May 18, $35 per character), which allows you to continue playing your existing character on WoW Classic while also advancing to Burning Crusade Classic.
After the Pre-Patch releases, WoW Classic players will choose whether to progress each of their characters to Burning Crusade Classic with the rest of their realms or continue playing the original WoW Classic content on brand-new Classic Era realms. Players who wish to experience the best of both worlds will be able to use the optional Character Cloning Service (available on May 18, $35 per character).
All the characters that you created and played before servers come down for the Pre-Patch will appear on the same realms. It means that you'll see all your pre-existing characters in both versions of the game.
If you click the "Clone" icon, a confirmation window with more information will appear. It shows the "Clone" date of the character.
Click "Accept", and it will take you to the Shop interface, which will allow you to purchase the Character Cloning Service.
Upon completing the transaction, you can pay it.
Level 58 Character Boost
If you want to boost your character of Burning Crusade Classic to level 58, you can purchase the Dark Portal Pass (available on May 18, $39.99).
Everyone who wants to join the adventure in Outland with their friends will also have the option to purchase the Dark Portal Pass (available on May 18, $39.99), allowing them to boost one character of their choosing on Burning Crusade Classic to level 58 (It is limited to one per World of Warcraft account, and not usable on Blood Elf or Draenei characters).
The boosted character will receive some skills, items, and Classic TBC gold as below.
Apprentice Riding skill
Weapon skills up to level 58
Access to certain flight paths
A set of level 58 magic (green) quality gear
Up to four Runecloth Bags (14 slots each)
