Upgrading to Windows 2008 R2

Upgrade our testlab machine from Windows 2008 64bit Ent SP2 to Windows 2008 R2 (RC).

What is running on top of it:
- IIS
- Hyper-V

How to upgrade? Just put in Windows 2008 R2 RC DVD, click for upgrade. It will show the programs/apps that is not compatible, you will need to uninstall some of the apps (that not supported) to ensure a smooth upgrade.

It will then prompt KB957256. As for today, not be able to find this KB article.

We ignore it (cause in a test lab - you might want to test and test and test in a live environment).

After the upgrade, the installation wizard will transfer your files, settings and programs to the R2 environment.

Within 2 hours, everything is up and running. It is the easiet upgade we ever had.

Good job MSFT.
