Verify that all components meet basic compatibility requirements before upgrading vCenter Server.
About this task
Upgrading the operating system of a vCenter Single Sign-On 5.1 machine from Windows 2003 to Windows 2008 to meet the operating system requirements may result in symptoms similar to knowledge base article 2036170.
If you have solutions or plug-ins, check the VMware Product Interoperability Matrix. See http://www.vmware.com/resources/compatibility/sim/interop_matrix.php
- The installation path of the previous version of vCenter Server must be compatible with the installation requirements for Microsoft Active Directory Application Mode (ADAM/AD LDS).
The installation path cannot contain any of the following characters: non-ASCII characters, commas (,), periods (.), exclamation marks (!), pound signs (#), at signs (@), or percentage signs (%).
If your previous version of vCenter Server does not meet this requirement, you must perform a fresh installation of vCenter Server.
- Verify that the vCenter Server system is not an Active Directory primary or backup domain controller.
- Update any ESX/ESXi 4.1 hosts to version 5.x.
- If you have ESX 4.x hosts that you choose not to upgrade, you must remove them from the vCenter Server inventory.
- If the vCenter Server 4.x environment that you are upgrading includes Guided Consolidation 4.x, uninstall Guided Consolidation before upgrading to vCenter Server 6.0.
