Downgrading a vSphere 4.x license to a ESX 3.5 license (1010533)

  • 522 Ratings


This article provides information about downgrading vSphere licenses to an older version such as VMware Infrastructure 3.x and answers the following questions:
  • How do I downgrade vSphere 4.x?
  • Can I purchase a VMware Infrastructure 3 license if I have already purchased a vSphere 4.x license?
  • How do I purchase a VMware Infrastructure 3 license?


After the release of vSphere 4.x, you can no longer purchase older versions. You must downgrade the license.
To downgrade your license, see Downgrading a license key to VI3 in Downgrading license keys in My VMware (2006975).
  • The downgrade option is not available with ESXi 4 Single Server, vSphere 4 Essentials, and vSphere 4 Essentials (Plus).
  • You can only downgrade new orders, and you must downgrade the whole order. 
  • License keys are not decreased or affected by a downgrade.
  • The downgrade process cannot be reversed.
  • If a license has been upgraded from VI3 to vSphere 4, you do not need to downgrade.
  • If you have made a new order and you do not have the option to downgrade the licenses, file a Support Request. For more information, see Filing a Support Request in My VMware (2006985).

Additional Information

vMotion functionality is only available for licenses downgraded from vSphere Enterprise and vSphere Enterprise Plus.
