Because the Chaos data center is being relocated, certain players may find they are no longer playing on a desirable World. In order to address this issue, players will be allowed to transfer from Worlds within the Chaos data center to Worlds within the Elemental, Gaia, Mana, Aether, or Primal data centers free of charge for one week.
Residents in the North American region playing on the Chaos data center may begin to experience issues with latency after the transition. We ask that you try the game after the transfer, and if you experience connectivity issues disruptive to gameplay, consider using the free World transfer service while it is available.
the same reasons can be applied to this datacenter move, and I don't see anything that makes this transfer different than the previous one, as long as it always is a datacenter being relocated.
