In the previous chapter of Windows Server 2008 R2 Essentials we looked at performing a clean installation of Windows Server 2008 R2. Whilst this approach is acceptable in some instances, it is probably more common that Windows Server 2008 R2 will be installed as an upgrade to a previously installed version of Windows. In this chapter the steps involved in performing an upgrade to Windows Server 2008 R2, together with supported upgrade paths will be covered in detail. Contents
Windows Server 2008 R2 Upgrade PathsBefore performing an upgrade to Windows Server 2008 R2 the key prerequisite is that the currently installed operating system provides an upgrade path to the chosen edition of Windows Server 2008 R2. Whilst it was possible to upgrade to the original version of Windows Server 2008 from a somewhat wide range of older operating systems, the upgrade options provided by the R2 version are considerably more limited. In fact, Windows Server 2008 R2 may not be upgraded from any of the following operating systems: Windows® 95, Windows 98, Windows Millennium Edition, Windows XP, Windows Vista®, Windows Vista Starter, or Windows 7, Windows NT® Server 4.0, Windows 2000 Server, Windows Server 2003 RTM, Windows Server 2003 with SP1, Windows Server 2003 Web, Windows Server 2008 R2 M3, or Windows Server 2008 R2 Beta, Windows Server 2003 for Itanium-based Systems, Windows Server 2003 x64, Windows Server 2008 for Itanium-based Systems, Windows Server 2008 R2 for Itanium-based Systems In fact, it is only possible to upgrade from Windows Server 2008 to Windows Server 2008 R2 and even then with the following restrictions:
For example, it is possible to upgrade from a 64-bit Windows Server 2008 Standard to Windows Server 2008 R2 Standard, Enterprise or Datacenter editions. It is not, however, possible to upgrade from Windows Server 2008 Enterprise to Windows Server 2008 R2 Standard (since this constitutes a downgrade in functionality).
How an Upgrade to Windows Server 2008 R2 WorksDuring the Windows Server 2008 R2 upgrade process the files, folders and applications associated with the previously installed Windows version are relocated to a windows.old folder and all user settings stored. Once this task is complete, a clean installation of the new operating system is performed and the saved user settings migrated to the new environment. Upon completion of a successful upgrade the Windows Server 2008 R2 system will include all applications, settings and user files from the previous operating system installation.
