-          This attribute is not intended for the modification of vimAssets

-          Modification of VIM assets during the lifetime of a VNF instance is

-          been on boarded into the VIM before the VNF is instantiated.
+          The Grant response allows the NFVO to pass to the VNFM VIM assets
+          related to the VNF package that is identified by the vnfdId attribute
+          in the corresponding Grant request. The NFVO may send in each Grant
+          response the full set of VIM assets related to the VNF package defined
+          by the vnfdId in the related Grant request, but shall send this information
+          if the vnfdId in the related Grant request differs from the vnfdId passed
+          in the previous Grant request, or if the Grant response is related to an
+          InstantiateVnf operation.
+          The set of VIM assets shall not change between subsequent Grant responses
+          if the vnfdId has not changed. During each LCM operation occurrence,
+          the VIM assets that relate to the VNF package identified by the current value
+          of the vnfdId attribute in the “VnfInstance” structure shall be used by the
+          VNFM for newly created resources. If the VNF package identifier of the
+          VNF instance has been updated, VIM assets that relate to the previously-used
+          VNF package(s), and that were communicated in previous Grant responses,
+          apply to existing resources.
