Microsoft ended extended support for Windows Server 2003 on July 14, 2015. If you are running Windows Server 2003, this may put your applications and business at risk, since there may be no security or software updates. You can still move a Windows Server 2003 VM to Azure, and receive assistance in troubleshooting issues that concern running Windows Server 2003 on Azure. However, this support is limited to issues that don't require OS-level troubleshooting or patch.

Machines running Windows 2003 will no longer receive Microsoft support and may not receive further security updates. Additionally, many compliance requirements include being on a currently supported operating system.
Migrating your applications to Azure instances running a newer version of Windows Server is the recommended approach to ensure that you are effectively leveraging the flexibility and reliability of the Azure cloud. Pre-configured images with different combinations of Windows and SQL Server are available in the Marketplace and enable you to run any compatible solution on our cost-effective, high-performance, reliable cloud computing platform. For more information, see Windows Server 2003 migration strategy.
The Azure support team continues to offer assistance in troubleshooting issues that concern running Windows Server 2003 on Azure. However, this support is limited to issues that don't require OS-level troubleshooting or patches.
A: Windows Server 2003 32-bit has the same level of support as 64-bit, but both operating systems are past their end of support date. Microsoft does not support operating systems that are past their End of Support date without a Custom Support Agreement (CSA). However, the Azure infrastructure is supported. See Microsoft server software support for Microsoft Azure virtual machines for more information.

The upgrade process from Windows Server 2003 to Windows Server 2008 requires free disk space for the new operating system image, for the Setup process, and for any installed server roles.For the domain controller role, the volume(s) hosting the following resources also have specific free disk space requirements:
The free space on the %WinDir% volume must be equal or greater than the current size of the resources that are listed and their subordinate folders when they are located on the %WinDir% volume. By default, dcpromo includes the Active Directory database and log files under %Windir%. In this scenario, their size would be included in the free disk space requirements for the %Windir% folder. However, if the Active Directory database is hosted outside any of the folders here, the hosting volume(s) must only contain additional free space equal to at least 10% of the current Active Directory database size or 250 MB, whichever is larger.The free space on the volume that hosts the log files must be at least 50 MB.When you install Active Directory service in Windows Server 2003, the Active Directory database and log files are installed, by default, under the %WinDir%\NTDS folder. In this scenario, the NTDS.DIT database file and all the log files are temporarily copied to the quarantine location and then copied back to their original location. Therefore, additional free disk space is required for the resources. However, the SYSVOL directory that is also located under the %WinDir% directory is moved and not copied. Therefore, it requires no additional free space.After the upgrade, the space that was reserved for the copied resources will be returned to the file system.
Because of fundamental changes that are implemented in Windows Server 2008, some server applications may require pre-upgrade and post-upgrade preparation. In some cases, the server applications must be removed before upgrading from Windows Server 2003 to Windows Server 2008 and reinstalled after the upgrade.
You can upgrade a Windows Server 2003-based computer that is running Microsoft Windows SharePoint Services to Windows Server 2008. Typically, Windows Server 2003-based computer that is running SharePoint Server 2007 to Windows Server 2008 is a supported upgrade scenario.
Currently, upgrade of Windows Server 2003-basedcomputers that are running Office Communications Server 2007 to Windows Server 2008 is not supported. Later versions of Windows Server 2008 may support such upgrades.
