Upgrade path from 2003 to version 2.0

[Former Member]

I developed a web app for a customer that includes well over 100 different proxies. The customer is asking about upgrading to Nco 2.0. Will I have to re-generate all those proxies if we move forward with the upgrade?

The upgrade from NCo 1.x to 2.0 shouldn't be a big issue, even if you have many proxies:

- In most cases the proxies generated by 1.x version should work.

- Anyway it's recommended and easy to regenerate: Just select all .sapwsdl files and say "Run Custom Tool".

- NCo 2.0 also has the "Update Metadata feature" in case that the RFC functions have changed in the backend.
