About 10 minutes on a normal wallet and PC. Longer for many addresses in the wallet and on a slow CPU. You don't need to rescan as long as there is no chance that wallet received payments while it was "down".

Its because of a migration to a bigger server. And I need the wallet because there are multiple "user accounts" inside...
How long does it take to rescan in general?

You could also just transfer the coins to a new wallet on the new machine.

Just closing bitcoin, copying the wallet.dat (after moving but not deleting any previous important wallet), and restarting with the bitcoind -rescan option is sufficient to move a wallet to another machine. If you don't already have a blockchain downloaded, it will be a long time before that bitcoin is ready though; copying an existing complete 12GB datadir can save a day of re-downloading and processing the blockchain.

I can't think of many scenarios outside of restoring a backup where you'd put an existing wallet.dat up on a server.

And what should I do if i have a webserver and want to keep the offline time low? I cant wait until some GB are transferred between the server.. Or is there no other stable possibility?

You'll want to just copy the whole Bitcoin data directory with the wallet.dat and subdirectories, so you don't have to download the blockchain again.

Is it true, that nowadays (after version 0.3.2), you can just copy the wallet to the new location - without --reindex or deleting the bulk datas?

Do people ever transfer BTC by just mailing someone a wallet.dat?

You'ld want to encrypt it first -- using TrueCrypt, for example, and then send only the encrypted archive:

For older clients you need to delete blk0001.dat and blkindex.dat, and let it redownload the block chain...

Don't trust "BBOD The Best Futures Exchange"
For anyone googling this in the future - note that the -rescan switch was added in the 3.20 client, I ran into problems when I was working with two wallets because I was using the 3.19 client and trying to use -rescan.

Copy the wallet from that directory on the old computer to the new one, then run the bitcoin client with the -rescan switch.
