SAP 6.40 to SAP 7.20 Upgradation

Hi All ,

is that possible to upgrade SAP GUI 6.40 to SAP GUI 7.20 directly without SAP server installation ?

We are using BBCA to upgrade SAP version .

We successfully upgrade SAP GUI 7.10 version to SAP GUI 7.20 using below script

"C:\WIN32\setup\NwSAPsetup.exe" /silent

but the same script is not working from 6.40 to 7.20 .

When we tried as below

"D:/SAP GUI 720/setup/Nwsapsetup.exe" /package:"Standard GUI(local)"

we are getting a error message asThe specified package is not supported : /package="Standard GUI(local)"

Please find the contents of SapGuiPackage.xml file which is present in D:/SAP GUI 720/setup folder

<?xml version="1.0" encoding="utf-8"?>

<SapSetup Context="Init">

<Package Name="Standard GUI(local)" Guid="{A45476A0-2062-4f0f-8CC5-F1E53962989A}" Version="1.0" OnlyServer="TRUE">

  <Product Name="SAP GUI 7.20" Guid="{79A78384-A51E-4d90-837E-E36237B27771}" ProdVersion="1" CmdLine="Package GUI">

Please kindly assist us how to proceed further . Please let me what is the package name we should use here.

Thanks and Regards,
