Delta between WAS 6.20 and WAS 6.40
I'm trying to understand the difference between a WAS 6.20 and a 6.40 installation.
Are there any delta-documents available with an overview of additional functionalities/changes?
Are there any restrictions for migrating to a WAS 6.40: f.i. does a SAP CRM 4.0SP9 installation run on a WAS 6.40?
Will the upgrade impact the CRM applications/middleware?
Where can I find this information myself?
Thx in advance & kind regards,
