Do they restart the realms, do you have to log out?

Or are you just suddenly able to train flying and head off your merry way?

You will have to log all the way out before you can access Cataclysm content. There won't be any planned server restarts or that sort of thing.

Every hour another post like this pops up, I seriously think there needs to be a search reminder before you post. Anyway below is a blue quote which I found by using BlueTracker AND Searching Google!

Q. If I've already installed World of Warcraft: Cataclysm and upgraded my account, will I need to do anything special at midnight in order to access the new expansion content
A. Once Cataclysm is marked live on all realms, simply exit out to the login screen (the one featuring Deathwing's toothy grin) and log back in. This will provide you full access to the new content -- including the goblin and worgen races and level 80-85 zones.

If you're concerned that you won't know when to re-log, we've got you covered. After Cataclysm is marked live, if you're still logged in and are playing from an upgraded client, you'll be prompted with official in-game messaging that will instruct you to log out and then log back in.

Thx for the answer
