Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The process of moving to Windows Server R2 might vary greatly depending on which operating system you are starting with and the pathway you take.

We use the following terms to distinguish among different actions, any of which could be involved in a new Windows Server R2 deployment. Installation is the basic concept of getting the new operating system on your hardware. Specifically, a clean installation requires deleting the previous operating system. Upgrade means moving from your existing operating system to Windows Server R2, while staying on the same hardware. Even while staying on the same hardware, some server roles might require specific steps to ensure a smooth upgrade.

For detailed information about upgrading by any of these methods to Windows Server R2, see upgrade options. Migration means moving from your existing operating system to Windows Server R2 by transferring to a different set of hardware.

Before you start a clean installation of Windows Server R2, you should perform the following steps. The following are estimated system requirements for the Windows Server R2.

If your computer has less than the "minimum" requirements, you will not be able to install this product correctly. Actual requirements will vary based on your system configuration and the applications and features you install. Consult documentation for each of the server roles you intend to deploy for more details about the resource needs of particular server roles.

For the best results, conduct test deployments to determine appropriate system requirements for your particular deployment scenarios. Processor performance depends not only on the clock frequency of the processor, but also on the number of processor cores and the size of the processor cache. The following are the processor requirements for this product:. If you create a virtual machine with the minimum supported hardware parameters 1 processor core and MB RAM and then attempt to install this release on the virtual machine, Setup will fail.

To avoid this, do one of the following: Allocate more than MB RAM to the virtual machine you intend to install this release on. Once Setup has completed, you can change the allocation to as little as MB RAM, depending on the actual server configuration. In the command prompt that opens, use Diskpart. Close the command prompt and proceed with Setup. The following are the estimated minimum disk space requirements for the system partition.

Be aware that 32 GB should be considered an absolute minimum value for successful installation. For the smallest possible installation footprint, start with a Server Core installation and then completely remove any server roles or features you do not need by using Features on Demand.

The system partition will need extra space for any of the following circumstances: If you install the system over a network. Computers with more than 16 GB of RAM will require more disk space for paging, hibernation, and dump files.

Disconnect UPS devices. If you have an uninterruptible power supply UPS connected to your destination computer, disconnect the serial cable before running Setup. Setup automatically attempts to detect devices that are connected to serial ports, and UPS equipment can cause issues with the detection process. Back up your servers. Your backup should include all data and configuration information that is necessary for the computer to function.

It is important to perform a backup of configuration information for servers, especially those that provide network infrastructure, such as Dynamic Host Configuration Protocol DHCP servers. When you perform the backup, be sure to include the boot and system partitions and the system state data. Another way to back up configuration information is to create a backup set for Automated System Recovery. Disable your virus protection software. Virus protection software can interfere with installation.

For example, it can make installation much slower by scanning every file that is copied locally to your computer. Provide mass storage drivers. If your manufacturer has supplied a separate driver file, save the file to a floppy disk, CD, DVD, or Universal Serial Bus USB flash drive in either the root directory of the media or the amd64 folder. To provide the driver during Setup, on the disk selection page, click Load Driver or press F6.

You can browse to locate the driver or have Setup search the media. Be aware that Windows Firewall is on by default. Server applications that must receive unsolicited inbound connections will fail until you create inbound firewall rules to allow them. Check with your application vendor to determine which ports and protocols are necessary for the application to run correctly. For all editions, you have 10 days to complete online activation, at which point the evaluation period begins and runs for days.

During the evaluation period, a notification on the Desktop displays the days remaining the evaluation period except in Windows Server Essentials. You can also run slmgr. All evaluation versions are fully functional during the evaluation period, although booting to Safe mode is not available. The Windows Server Standard and Windows Server Datacenter editions come with the activation key pre-installed. After the day evaluation period elapses, the server warns you in various ways depending on the edition:.

The operating system will shut down every hour. Windows Server Essentials: you receive warnings on the Desktop and on the dashboard, but the server does not shut down. The resulting virtual machine has the following characteristics:.

The Hyper-V server role must be installed. Download the VHD file to a convenient location. Start Hyper-V Manager. On the Action menu, point to New , and then point to Virtual Machine. After completing the New Virtual Machine wizard, check Hyper-V Manager to verify that the virtual machine was successfully created. Right-click the new virtual machine and point to Settings. In the left pane, click IDE Controller 0.

In the right pane, point to Hard Drive , and then Add. In the menu that opens, click Virtual Hard Disk and point to Browse Configure the network adapter for the resulting virtual machine: right-click the virtual machine and select Settings. In the left pane, click Network Adapter. In the menu that appears, select one of the network adapters of the virtualization server, and then click OK.
