Max, honestly, I think you are a well-intentioned guy, but allow me to make a critical comment, the way you conducted the wipe / update is a real disaster.
Maintaining the two servers now is to postpone death, dividing the community.
As I said yesterday, your server is good for farm and very receptive to new players aiming at the end-game. If the wipe had been thinking from the beginning, with a massive release of the new Viserion, it would have been really cool. However, this was not his option.
My suggestion for you to save the community. Cancel the launch of today, keep it as Beta, redo the opening announcements for new viserios in ex...15 days, think about some benefit for your current players (to encourage them to migrate, Ex: full clan for larger guilds...), release Deadz at the start of the new server, which is based on Farm. Deadz helps a lot in boss, augment, up etc ... Blocking after some time, but give people time to reach the end game.
