Well, I would start with LSMW. There are many pre-defined programs delivered by SAP to help you migrate the data. If there is no LSMW routine for you purpose, then I would go with BDC and/or BAPI. I haven't ever wored with IDOCs, so I don't know how they would fit in to the mix.

Hi,

I would prefer BAPIs wherever availale in place of a BDC.

SAP also releases different migration tools.. And these tools used directly for OS/DB migration. These tools will migrate the data automatically from source to target systems.

But one has to be trained and certified to use these tools.

If we are not aware of these tools then treat the source system as a legacy system and migrate data using standard tools like BDC, LSMW
