Verify that all components meet basic compatibility requirements before upgrading vCenter Server.
Verify that your system meets the hardware and software requirements. See vCenter Server for Windows Requirements.
If you have solutions or plug-ins, ensure their compatibility with the vCenter Server version to which you are upgrading. See VMware Product Interoperability Matrices.
- 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 must contain only ASCII characters. Extended ASCII and non-ASCII characters are unsupported.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 ESXi 5.0, ESXi 5.1, or ESXi 5.5 hosts to version 6.0 or later.
- If you have ESXi 5.0, ESXi 5.1, or ESXi 5.5 hosts that you choose not to upgrade, you must remove them from the vCenter Server inventory.
- Upgrade VMware Host Profiles to version 6.0 or later.
Host Profiles is a vCenter Server tool for designing and deploying ESX and ESXi hosts. Ensure that you are using Host Profiles version 6.0 or later. See Knowledge Base article KB 52932.
- Upgrade vSphere Distributed Virtual Switch (DVS) version 6.0 or later.
You must upgrade to DVS version 6.0 or later before upgrading to vCenter Server 6.7. See Knowledge Base article KB 52826.Note: DVS version 6.0 or later supports only Network I/O Control version 3. If you are using an earlier version of Network I/O Control, you must upgrade to Network I/O Control version 3. For more information, see the vSphere Networking documentation.
- Verify that you can upgrade your vCenter Server version using an Embedded Linked Mode topology to vCenter Server 6.7 Update 2.
Note: vCenter Server deployments using an external Platform Services Controller will not be supported in a future vSphere release. Deploy or upgrade to a vCenter Server deployment using an embedded Platform Services Controller. For more information, see Knowledge Base article KB 60229.
- Upgrading from vCenter Server 6.0 using an Embedded Linked Mode topology to vCenter Server 6.7 Update 2 is supported.
- Upgrading from vCenter Server 6.5 Update 2 using an Embedded Linked Mode topology to vCenter Server 6.7 Update 2 is supported.
