On 2011-09-13, the VDT team announced the release of VDT 2.0.0p29.
If you installed VDT 2.0.0 after VDT 2.0.0p29 was released on 2011-09-13, you do not need to do any of these update operations because you will have 2.0.0p29.
We strongly encourage users to update the VDT using the VDT updater script: VDT Updater Instructions
If you really want to do it the hard way, instructions for updating by using Pacman directly are available on another page. This method is hard to follow and error prone.
