Upgrading for Wrath of the Lich King

To ensure a smooth transition to Wrath of the Lich King, we recommend that players who have newly upgraded their accounts, log into the game and log out completely for a short period of time in order for their account to fully update.

Q u o t e:
thanks for the heads up.
Would you happen to know if the servers will need to be restarted when LK goes live or will we just see the zepplins/boats coming and going on schedule?

The zeppelins and boats will be running on schedule.

Q u o t e:
Would 5 or so minutes suffice?

That would probably be a safe bet.

Q u o t e:
I am still confused if people can upgrade that means they can have a DK like now right?
um...

Northrend will not be available until 9PM PST for the US.
