Pre-Upgrade Preparation

Before you start the upgrade process, there are several things you need to do to prepare your server. These include:

Backing Up Your Data

Before you make any changes to your server, it’s always a good idea to back up your data. This will ensure that you have a copy of your important files in case something goes wrong during the upgrade process. You can use Windows Server Backup or any other backup solution of your choice.

Checking System Requirements

Before you upgrade to Windows Server 2019, you need to make sure your server meets the system requirements. These include:

System Requirements
Minimum
Recommended
Processor
1.4 GHz 64-bit processor
2 GHz or faster multi-core processor
RAM
512 MB
4 GB or more
Storage Space
32 GB
64 GB or more
Network Adapter
1 Gbps
10 Gbps or more

Make sure your server meets these requirements before proceeding with the upgrade.

Checking Application Compatibility

Before you upgrade to Windows Server 2019, you need to make sure your applications are compatible with the new operating system. Check with your software vendors to ensure that their applications are supported on Windows Server 2019. If you’re using custom applications, test them in a non-production environment before upgrading.

Checking Driver Compatibility

Make sure all your hardware drivers are compatible with Windows Server 2019. Check with your hardware vendors to ensure that they have drivers available for the new operating system. Installing incompatible drivers can cause system instability and other issues.

Upgrade Process

Once you’ve completed the pre-upgrade preparation, you’re ready to start the upgrade process. Here’s how:

Step 1: Download Windows Server 2019

The first step is to download the Windows Server 2019 ISO file from the Microsoft website. You can download the evaluation version or purchase a license if you’re ready to upgrade. Make sure you download the correct version based on your server’s architecture (x86 or x64).

Step 2: Mount the ISO File

After downloading the ISO file, you need to mount it on your server. You can do this by right-clicking on the file and selecting “Mount” or by using a third-party tool like Daemon Tools or WinCDEmu.

Step 3: Run the Setup Program

Once the ISO file is mounted, navigate to the root folder and run the setup.exe file. This will launch the Windows Server 2019 setup program. Follow the on-screen instructions to start the upgrade process.

Step 4: Select Upgrade Option

When prompted, select the “Upgrade” option to perform an in-place upgrade. This will preserve your existing applications, data, and settings. Alternatively, you can perform a clean install if you prefer to start from scratch.

Step 5: Follow On-Screen Instructions

Follow the on-screen instructions to complete the upgrade process. The setup program will copy files, install updates, and reboot your server several times. Make sure you don’t interrupt the process or turn off your server during this time.

Step 6: Verify Upgrade

Once the upgrade process is complete, verify that your server is running Windows Server 2019. You can do this by checking the version number in the System Properties dialog box or by running the “winver” command in the Command Prompt.
