How hard would it be for them to just change the unique identifier key in the database for each housing ward so they could all exist on the new server. So if the current key is say for my house is something like Mist10Sub37 in the database, in a merge all they would have to do is add a server prefix at the beginning or on the end i.e. Mist10Sub37AS using Asura as an example.

I know... logic... how dare I.
