Hi Experts ,

I just want to know about downloading and uploading the webdynpro component as it is.

the requirement is : all of sudden my client want to shift his system from ECC 6 to S/4 Hana

so I just want download my webdynpro Applications on to my desktop and to upload from the desktop
to S/4 Hana. Its just like downloading smartform/smartstlye download. Utilities ->Download in XML. is there any option possible in Webdynpro to get it downloaded?

I saw SAPLINK plugin (ZSAPLINK) but I really did not understand what to do . I simple created a ZSAPLINK program in SE38 and copy and pasted the ZSAPLINK and tried executed but no use. so kindly help me step by step wise as layman can understand to download the webdynpro application.
