We are planning to upgrade from SAP R/3 4.6C to SAP ERP 6.0..
Our other running modules are CRM 4.0 - BW 3.5 - Portal 2004s. We also use sap internet sales b2b and b2c
What should be the upgrade schedule for all modules? Upgrade all at once? If not what sould be the order ?
Thank you all for your replies ..
