Well, we have the answer, and itâ€™s thanks again to WHS reader condition_unknown, who has written up a walkthrough for the FAQ section of the We Got Served forums.
Hereâ€™s what you need to do:
Upgrading Windows Home Server From a Beta or 120 Day Evaluation Version
The upgrade is actually a server reinstallation as opposed to a new install. This will keep all your existing files and storage pool intact. If this was a new install the drives specified for the storage pool would be formatted and one would lose the data on the drive. Make sure you make note of the users, passwords settings and Windows Live ID you had used in the previous install because you will have to re-enter this information. Also write down the fixed IP address and DNS names you used in the previous install.
1. Set BIOS to boot from optical drive.
2. When prompted, hit any key to boot from the drive.
3. When the installation window appears, select â€˜Reinstall Serverâ€™.
4. Install will take over an hour and several reboots will occur.
5. After install finishes, you will have to setup your administrator password. Make sure that you use the same password as you had previously.
6. Install Ethernet drivers.
7. Open the Network properties for you network adapterâ€™s TCP/IP settings and put in the values you had previously used.
EDIT: Note that in December 2009 Microsoft changed the period of the Trial Version to 30 Days - so it is no longer a 120 Day Trial
