Should you upgrade to Windows Server 2016?

Compared with previous version, Windows Server 2016 has made a lot of improvements and optimization, and introduced some useful features, such as, Nano Server, PowerShell 5.0, Windows Server Containers, Active Directory Domain Servers (AD DS), Active Directory Federation Servers (AD FS), Hyper-V Containers, etc.

Next, I’ll introduce you some new features in detail.

  • Power Shell 5.0: This command line utility is installed by default in Windows Server 2016. And it has significant upgrades across security, usability, and new feature, such as, Windows PowerShell Desired State configuration.

  • Windows Server Containers: Windows Containers provide application isolation through process and namespace isolation technology by sharing a kernel with the container host and all other containers running on the host.

  • Hyper-V Containers: This type of containers offer further deployment options for administrators that can provide increased isolation. In specific, it encapsulates each container in a lightweight virtual machine and supports containerized applications with a greater degree of security by making use of Microsoft’s hypervisor.

In sum, Windows Server 2016 has better security, virtualisation, automation, efficiency, availability and performance. So, if you want to enjoy these features, you can upgrade from Windows Server 200, 2008, 2012 to 2016.

  • Processor: 1.4Ghz 64-bit processor

  • RAM: 512 MB

  • Network: Gigabit (10/100/1000baseT) Ethernet adapter, 1Gbps connection is ideal.

  • Optical Storage: DVD drive (if installing the OS from DVD media)

2. Make sure the applications are compatible. Since Windows Server 2016 only supports x64 bit operating system, you need to check if the installed programs is x64 bit. If not, it may work improperly after the upgrade.

3. Ensure all Windows updates are complete and no virtual machines running. If there are any upcoming updates in previous version, such as, Server 2012, the upgrade process may fail.

4. Verify if your disk has enough space. The minimal space for core installation is 32GB, but you may need more space. Because you may need to install new applications, save files and folders on the system drive in the future.
