Moving Exchange Database to another partition: HELP

Tech-Archive recommends: Speed Up your PC by fixing your registry

Well, i have a serious space issue and want to move the exch databases to
another partition.

First, I found this:
http://www.microsoft.com/technet/prodtechnol/sbs/2003/maintain/movedata.mspx
but the link provided in the Exchange move section is invalid (although i
did get the Users Shared Folders moved successfully)

Then, I found this: http://support.microsoft.com/kb/270693/en-us but when I
got to instruction #6 i had to stop. There is no DATABASE tab.

Is there anyone out there who could direct me to instructions to get this
move done -- i'm fairly desperate.

Thanks in advance!
Susan
