For how to move the databases, see:

As for how long it takes... that depends...
*are you moving them to a different physical disk or another partition?
*are they fragmented?  If so, how badly?
*how fast are the disk(s)?  5400 RPM?  7200 RPM?  10000 RPM?  15000 RPM?
*what else is running off the drives?
*are you using RAID?  If so, what level?  1, 5, 10, 0?

Don't bother answering these - in the end, to an extent, you can't answer these questions reliably... the point is how long it takes is a GUESS at best.  For 400 GB - to a TYPICAL new disk - I'd GUESS 2-4 hours.  But that's a guess.

It is very simple to do, how long it will take depends on the size but its not that long, your talking minutes not hours.

Start Exchange System Manager.
Open the administrative group that contains the database that you want to change.
Under Storage Group, right-click the mailbox store or the public folder store that you want to change, and then click Properties.
Click the Database tab.
Next to the database that you want to change, click Browse, and then specify a new drive or folder location for the files.

When was the last time you moved 400 GB?  I've moved dozens of GB and it's taken 30-45 minutes.  And if moving from one partition to another on the same disk - it's taken me HOURS for a 40 GB information store.

Missed the size part. and Yeah OP he is right if it is 400g it will be hours no minutes.

Bad reading skills on my part.

My recommendation would be to not move the database at all.

If you have a 400GB store your obviously using the Enterprise edition of exchange.

In this case create a new database and move the mailboxes to it.  This gives you the advantage of a clean store with no White space or frgmentation with the added bonus of very litle downn time.
