Windows Server 2003: Last Call

        Despite Microsoft warning about end of life for Windows Server 2003 as early as April 2013, many organisations are yet to begin their migration away from the server platform. Worse still, many organisations and IT pros are unaware of the huge financial costs and security risks should they continue running Windows Server 2003 past the end of life date.

Reports from HP claim that more than 11 million systems are still running Windows Server 2003. With fewer than 240 days left until end of life, this a huge problem as the estimated time required to migrate a datacentre of 100 or more servers can range from a minimum of three months and upwards of 18 months.

If you own even one of those 11 million servers and you have yet to begin migration, you should be worried. Luck for you, the following guide will migrate you to a position of safety. We will cover the following:

• Windows Server 2003 End of Life date
• Understanding what end of support means for Windows Server 2003 and the associated impacts
• An outline of how to migrate Windows Server 2003 
• Resources to aid migration


Windows Server 2003 End of Life date

According to the Microsoft Support Lifecyle section on 14 July 2015, Microsoft will end extended support on all versions of Windows Server 2003/R2.

From then on, this means no more updates or patches from Microsoft, which can result a less secure and less stable infrastructure for your business. What this really means:

• Maintenance Costs – running legacy servers is expensive. Intrusion detection systems, advanced firewalls and network segmentation are required to protect a now vulnerable Windows Server 2003 platform. You will also have increasing cost from maintaining aging hardware. Current estimates in a TechNet post from Alex Fu place the cost of custom support post end of life at US$200,000 on average. In a Q&A with David Mayer, practice director of Microsoft Solutions for Insight Enterprises, he estimated a support cost of $1500 per server per year.

• No Updates – there will be no more updates to fix bugs, performance issues and security vulnerabilities. To put this into perspective, 2013 saw the release of 37 critical updates for Windows Server 2003/R2. Past the end of life date, these critical issues will remain unfixed leaving you open to cybersecurity dangers such as malicious attacks or electronic data loss.

• No Compliance – once support ends, your organisation will almost certainly fail to meet industry wide compliance standards. Regulations such as HIPAA, PCI, SOX & Dodd-Frank all require regulated industries to run on supported platforms. The impact is twofold: Non-compliance could result in the loss of business, while high transaction fees and penalties from non-compliance could dramatically increase the cost of doing business.

• Software and Hardware Compatibility Issues – new software and hardware devices will not be built to integrate with Windows Server 2003. Sticking with a legacy server means you will likely run into compatibility issues and may not be able to run new instances of software or communicate with the latest devices.

• No Safe Haven – without continued support from Microsoft, virtualized and physical instances of Windows Server 2003/R2 and Microsoft Small Business Server (SBS) 2003 will not pass a compliance audit.


How to migrate from Windows Server 2003

Do not underestimate the task that lies ahead. Migrating applications and server workloads is no easy task. Worryingly, a study by App Zero suggests that 62 per cent of organisations do not have a plan to upgrade or migrate, or even know that EOS is coming.

Thankfully, Microsoft has released the Windows Server 2003 End of Service site, which contains a wealth of resources to help you plan migration. Central to this is the Microsoft four-step migration process, which involves discovering, assessing and targeting workloads and software before selecting the right migration plan. Let’s look at it in more detail:

• Discover – first up is discovering and cataloguing all the software and workloads that are running on Windows Server 2003/R2 at present. Download the Microsoft Assessment and Planning toolkit as this will be a worthy support document.

• Assess – now you have a list it’s time to analyse and categorise all your applications and workloads based on type, criticality, complexity and risk. This helps you prioritise for migration as well as identify issues and opportunities.

• Target – in this step, you must choose a destination for each application and workload. This could be the perfect time to evolve your organisation to the next level and embrace the cloud. Microsoft offers a series of destinations for each application or workload which could include:

o Windows Server 2012 R2
o System Center 2012 R2 (Private Cloud) 
o Microsoft Azure (Public Cloud) 
o SQL Server 2014
o Office 365

• Migrate – now is the time choose a migration plan. Microsoft offers a fantastic Migration Planning Assistant which covers all four steps. Look for official Microsoft training courses to give you an in-depth understanding of the new platforms you are planning to migrate to.
