If you need a customization specification that is only slightly different from an existing specification, you can use the Customization Specification Manager to create a copy of the existing specification and modify it. For example, you might need to change the IP address or the administrator password.


You must have at least one customization specification.


  1. In the vSphere Web Client inventory, select Rules and Profiles > Customization Specification Manager and click VM Customization Specifications.
  2. Right-click a specification and select Duplicate.


A new specification is created. If the specification does not appear in the Name column, refresh the vSphere Web Client.
