Migrating Third-Party Solutions

For information about upgrading with third-party customizations, see the vSphere Upgrade documentation. For information about using Image Builder to make a custom ISO, see the vSphere Installation and Setup documentation.

Upgrades and Installations Disallowed for Unsupported CPUs

Comparing the processors supported by vSphere 6.0, vSphere 6.5 no longer supports the following processors:

  • Intel Xeon 51xx series
  • Intel Xeon 30xx series
  • Intel core 2 duo 6xxx series
  • Intel Xeon 32xx series
  • Intel core 2 quad 6xxx series
  • Intel Xeon 53xx series
  • Intel Xeon 72xx/73xx series

During an installation or upgrade, the installer checks the compatibility of the host CPU with vSphere 6.5. If your host hardware is not compatible, a purple screen appears with an incompatibility information message, and the vSphere 6.5 installation process stops.

Upgrade Notes for This Release

Important: vCenter Server 6.5 Update 1 supports upgrades and migrations from vCenter Server 6.0 Update 3 and above to vCenter Server 6.5 Update 1.

Important: Upgrades or migration of vCenter Server earlier than 5.5 Update 3b when the environment is with an external vCenter Single Sign-On to vCenter Server 6.5 Update 1 with an external Platform Services Controller are unsupported. For example, to upgrade or migrate vCenter Server 5.5 with an external vCenter Single Sign-On to vCenter Server 6.5 Update 1 with an external Platform Services Controller, you must first update to vCenter Server 5.5 Update 3b and then perform the upgrade or migration to vCenter Server 6.5 Update 1.

vCenter Server 5.5 Update 3b build numbers are:

  • vCenter Server 5.5 Update 3b, build 3252642
  • vCenter Server Appliance 5.5 Update 3b, build 3255668

Upgrades or migration of vCenter Server 5.5 and later with an embedded vCenter Single Sign-On to vCenter Server 6.5 Update 1 with an embedded Platform Services Controller are supported scenarios.

There is a change in the upgrade process when you upgrade to vCenter Server 6.5 Update 1. For instructions about upgrading vCenter Server and ESX/ESXi hosts, see the vSphere Upgrade documentation. 

Open Source Components for VMware vSphere 6.5

The copyright statements and licenses applicable to the open source software components distributed in vSphere 6.5 are available at You need to log in to your My VMware account. Then, from the Downloads menu, select vSphere. On the Open Source tab, you can also download the source files for any GPL, LGPL, or other similar licenses that require the source code or modifications to source code to be made available for the most recent available release of vSphere.

Functionality Caveats

The vSphere Client is written in an HTML5-based language and frameworks supported by all browsers. However, different browsers have different performance characteristics regarding the HTML5 standard. In particular, performance with Internet Explorer 11 can be slower than with other browsers, because of the rendering engine that Internet Explorer 11 uses. If you experience such issues, try using another supported browser.

Product Support Notices

  • The VMware Lifecycle Product Matrix provides detailed information about all supported and unsupported products. Check the VMware Lifecycle Product Matrix also for further information about the End of General Support, End of Technical Guidance, and End Of Availability.

  • VMware is announcing discontinuation of its third party virtual switch (vSwitch) program, and plans to deprecate the VMware vSphere APIs used by third party switches in the release following vSphere 6.5 Update 1. Subsequent vSphere versions will have the third party vSwitch APIs completely removed and third party vSwitches will no longer work. For more information, see FAQ: Discontinuation of third party vSwitch program (2149722).

  • As of vSphere 6.5, VMware is discontinuing the installable desktop vSphere Client, one of the clients provided in vSphere 6.0 and earlier. vSphere 6.5 does not support this client and it is not included in the product download. vSphere 6.5 introduces the new HTML5-based vSphere Client, which ships with vCenter Server alongside the vSphere Web Client. Not all functionality in the vSphere Web Client has been implemented for the vSphere Client in the vSphere 6.5 release. For an up-to-date list of unsupported functionality, see Functionality Updates for the vSphere Client Guide.

  • Cross vCenter Server provisioning, which was introduced in vSphere 6.0, is not supported across vCenter Server versions. The cross-vCenter provisioning operations not supported across different versions of vCenter Server include vMotion, cold migration, and cloning. For example, a vMotion operation from vCenter Server 6.0 to vCenter Server 6.5, and vice versa, are not supported.

  • VMware vCenter Operations Foundation 5.8.x is no longer offered, interoperable or supported with the release of vSphere 6.5. If you want to continue using vCenter Operations Foundation 5.8.x products, you can do so only with vSphere 5.5 and vSphere 6.0.

  • vSphere 6.5 is the final release that supports binary translation mode virtualization of operating systems. Future vSphere releases will not include binary translation mode. For more information, see

  • vSphere 6.5 is the final release that supports Software-Based Memory Virtualization. Future vSphere releases will not include Software-Based Memory Virtualization.

  • You cannot create new legacy (Record & Replay / uni-processor) Fault Tolerance virtual machines on vCenter Server 6.5 and ESXi 6.5 hosts. If you want to continue running legacy Fault Tolerance virtual machines, remain with ESXi 6.0 or earlier. Existing legacy Fault Tolerance virtual machines continue to be supported on ESXi hosts earlier than 6.5 and managed by vCenter Server 6.5.

    If you wish to upgrade ESXi hosts to 6.5, turn off legacy Fault Tolerance (do not only disable Fault Tolerance) on the protected VMs prior to upgrading. SMP-FT (multiprocessor Fault Tolerance) is not automatically enabled on the VM. You must manually turn on Fault Tolerance (which becomes SMP-FT) for VMs on the newly upgraded 6.5 ESXi host.
