First of all a big thank you to EII for setting up a new server to save unity.
Nagafen when will we know these plans, or at least the first phase so we can give our input?
As to the transfer I feel that for any player that requests the move, all items for characters on their account/s should be copied over to the new shard, this must include plots owned, buildings on plots, all items in buildings on plots, all items in characters vault and inventory plus all info such as all quests done.
If possible all players built structures such as workshops, bridges; walls etc would be a bonus if they could be transferred.
