Season of Mastery players can now transfer their characters for free to a Classic Era realm or to a Wrath Classic realm of the same ruleset (Normal or PvP). Please be advised that this transfer is one way only and final. Your decision cannot be changed or reversed.
As Kaivax mentioned here, we started opening the Free Character Migration service from Season of Mastery to both Classic Era and Wrath Classic realms earlier this week, and then had to disable it to resolve a bug. While we are hard at work on that, we want to take the opportunity to revisit our selection of destination realms. We’ve received a lot of feedback from SoM players expressing disappointment at the lack of options for Wrath Classic destination realms in particular, and we’ve decided that when the Season of Mastery Free Character Migration service returns, we will allow players to move to any Wrath of the Lich King Classic realm in their region that shares the same ruleset (PvE or PvP) with their source Season of Mastery realm.
Additionally, we’ll soon be removing the restriction from Classic Era realms that prevents players from having both Horde and Alliance characters on the same PvP realm. This should make it easier to consolidate your characters in the same place on Classic Era, should you choose to move your SoM characters there. We know many Classic Era players have gathered on realms such as Whitemane and Mankrik in the Americas or Firemaw and Pyrewood Village in EU, and due to that consolidation, this change seems appropriate.
We’re going to need some more time to configure and test all this, so we are aiming to enable the Season of Mastery transfer service the week of Nov 1 at the earliest. We know that Season of Mastery players have been waiting a long time for this, and we want to get your SoM characters moved over to Wrath Classic or Classic Era as soon as possible, and we also want to make sure that you have satisfactory options for destinations as well.
We really appreciate your patience, and we’re excited to see your SoM characters adventuring alongside us in Wrath Classic or Classic Era very soon.
