Yesterday morning I tried to install Web Deploy on 2 servers to migrate IIS data from old one ( Windows Server 2003 ), to the new one (Windows Server 2008).
The Windows server 2003 asked me to restart, I did, but restart failed and caused the server be out of service.
The Windows Server 2008 R2 does not ask any question but when I restarted it for another purpose, failed to restart!!!
So I strongly recommend you not to install this software. I am sure that this program is buggy and make you a lot of trouble for you.
