Due to queues and faction population differences between the highest and lower populated PvP realms, the following Free Character Migration will be available until 22 February 2012:

Alliance only:
From: Outland
To: Al'Akir (PvP)
To: Jaedenar (PvP)
To: Lightning's Blade (PvP)

Horde only:
From: Stormscale
To: Neptulon (PvP)
To: Shadowsong (PvE)
To: Spinebreaker (PvP)

Discussion on this particular migration:

Please note: FCM is opened based on realm population tracking and analysis, not by request. If you're looking for a specific migration (from realm A to realm B), you are in most cases better off using Paid Character Transfer, or you could end up waiting for a very long time.

Paid Character Transfers (PCT)
All English realms follow the regular PCT rules, found here:
