We are on CRM 5.0 and in the process of migrating to CRM2007. Our business process is such that we have many replication objects (BPs from CRM to ECC6, Sales transactions from CRM to ECC, Material, pricing from ECC to CRM) that flow back and forth via middleware.
Now the question is during or after the upgrade, do we need to do something different to make sure this works seamlessly as it does for us now? Or do we need to do initial and delta loads again?
Also regarding JAVA and ABAB development items, I am assuming we can just update these components to CRM2007 via technical master guide.
In IC Win client, we have done a lot of enhancements including inbox searches, new EEWB fields. Would we need to develop these all over?
Please send your replies and thoughts.
