Windows Server 2019 End-of-Life: Everything You Need to Know

Microsoft 365

Microsoft has ceased providing mainstream support, updates, and security patches for the Windows Server 2019 operating system (OS) as of January 2024. While the OS has served as a robust foundation for numerous businesses, unfortunately, continuing to use the outdated system will present significant risks and challenges that your organization can’t just overlook. 

Intelligent Technical Solutions (ITS) is a managed service provider (MSP) that has helped businesses manage and maintain their servers for over a decade. In this article, we'll dive into the following: 

  • The Dangers of Using an Obsolete Server OS 
  • Alternatives to Windows Server 2019 
  • Steps You Should Take During Migration 

With that information, you should be able to migrate your data safely and securely. 

Top 9 Risks of Sticking with Windows Server 2019 After its EOL

Continuing to use Windows Server 2019 after its EOL poses several significant risks and challenges for your organization. That's because Microsoft will stop providing regular security updates, bug fixes, and technical support. Take a look at some of the risks you might face: 

1. Security Vulnerabilities

The biggest danger is exposure to security vulnerabilities. Without regular security updates, any newly discovered vulnerabilities or exploits will remain unpatched, making your server infrastructure susceptible to cyberattacks, malware infections, and data breaches. 

2. Non-Compliance

Many regulatory authorities will require you to use supported and updated software to protect sensitive data in order to remain compliant. That means using an unsupported operating system like Windows Server 2019 could lead to compliance violations and legal repercussions.

3. Lack of Technical Support

After its EOL, Microsoft will no longer provide technical support for Windows Server 2019. That means you won't have access to official assistance for troubleshooting issues, which could lead to extended downtime and operational disruptions. 

4. Limited Compatibility

Software and hardware vendors focus on supporting newer operating systems. Continued use of Windows Server 2019 might cause compatibility issues with third-party applications, drivers, and hardware components, hindering your ability to run essential software and systems.

5. Decreased Performance and Reliability

Over time, using an unsupported OS might lead to performance issues, stability problems, and other technical challenges due to the lack of updates and optimizations. Newer Windows Server versions bring in improved features, performance enhancements, and security measures. You miss out on all those benefits by sticking with the unsupported Windows Server 2019. 

6. Inability to Scale

If your organization is growing or your IT needs are changing, using an outdated OS might limit your ability to scale and adapt to new requirements. That's because new applications and hardware will no longer be compatible with Windows Server 2019.

7. Loss of Vendor and Third-Party Support

When it comes to your server's OS, you do not want to be left behind. Vendors and third-party providers will also phase out support for Windows Server 2019 as time passes, leaving you without options for assistance when you encounter issues. 

8. Negative Impact on Reputation

Clients, partners, and stakeholders may view your organization as less technologically advanced or security-conscious if you continue using an unsupported OS, potentially harming your reputation. 

9. Higher Maintenance Costs

While it might seem cost-effective to avoid immediate migration, the long-term costs of maintaining an unsupported OS can become significant. Custom support agreements or emergency fixes can be expensive. 

Alternatives to Windows Server 2019

To avoid the abovementioned risks, you must find an alternative immediately. That means you must find a new OS compatible with your organization’s specific needs, existing applications, and hardware. It’s also essential to evaluate the features and benefits of each option so you can find the suitable alternative that aligns with your organization’s IT strategy and goals. 

Thankfully, there are quite a few options available that can meet those considerations. Here are some alternatives you can check out: 

1. Windows Server 2022

Before making the leap to a new server OS to replace your aging Windows Server, charting a detailed plan is essential. Remember, a well-thought-out and executed server migration strategy will pave the way for a seamless shift and minimize potential disruptions to your organization's IT setup. 

Here's a rundown of critical steps to ensure a smooth migration: 

Step 1: Assess Application Compatibility 

First, check if all the applications and services currently running on your Windows Server 2019 are compatible with the new OS version. Some might need updates or tweaks for optimal performance on the new platform. 

Step 2: Evaluate Hardware Compatibility 

Ensure your existing hardware meets the requirements specified for the new Windows Server version. Upgrading or replacing hardware components might be necessary. 

Step 3: Backup Data and Prepare Recovery Plans 

Before tackling the upgrade, create comprehensive backups of all vital data and configurations. A reliable backup and recovery plan is crucial in case any issues arise during the migration. 

Step 4: Perform a Thorough Security Audit 

Conduct a detailed security audit of your current Windows Server 2019 setup. As you migrate to a new OS, sensitive data will be in transit, increasing the risk of interception. Identify and address any security vulnerabilities to ensure a secure transition. Consider conducting another audit post-migration to reevaluate security measures. 

Step 5: Provide Training 

If the new OS introduces significant changes in interface or features, offer training sessions to your IT staff. Ensuring familiarity with the new environment will help prevent issues like misconfiguration. 

Step 6: Review Network Configurations 

Check your network settings for compatibility with the new OS. Adjust configurations that conflict with new features or obsolete functions to avoid complications. 

Step 7: Prepare for Downtime 

Anticipate potential downtime required for the migration process. Develop a schedule to minimize disruptions during the transition. 

Step 8: Test the Network Environment 

Create a test environment to simulate the migration process. Identify and resolve compatibility issues with applications, services, or configurations beforehand. 

Step 9: Communicate the Migration 

Inform your IT team, stakeholders, and end-users about the impending changes, potential downtime, and any necessary actions. 

Step 10: Document the Process 

Document each step of the migration, configurations made, and encountered issues. These records will serve as valuable references for future troubleshooting. 

Step 11: Craft Contingency Plans 

Be prepared for unforeseen challenges by drafting contingency plans. Include rollback procedures in case of unexpected hiccups during migration. 

Step 12: Seek Expert Assistance 

Consider engaging IT consultants or managed service providers specializing in Windows Server migrations if your organization lacks in-house expertise. Their experience and knowledge can ensure a smooth transition.
