Dec.EWM 9.3 Custom code Migration to S/4 HANA 2021 Embedded EWM

[Sagar_EWM27]

Hello Experts

We are migrating from Dec SCM EWM 9.3 to S/4 HANA 2021 Embedded EWM. Our goal is to migrate the custom code for this migration, and for that, we are referring to the attached Migration Guide "How to Migrate from SAP EWM (Business Suite) to EWM Based on SAP S/4HANA."

However, we have noticed that there is no clear process mentioned in section 3.1 of the guide for custom code migration. We intended to use the Import/Export mechanism but found that transaction codes like CG3Y and CG3Z are not supported in the source EWM system version 9.3.

Anyone has experience with such scenario & guide further on this? We explored other options like FM- ARCHIVFILE_CLIENT_TO_SERVER, but it is not suitable for us & is dependent on the service provider. 

Thanks & Regards,

Sagar
