I am for the first time getting involved in Data migration project in SD .
My question is what are the things that i need to Plan for Migration activities
1. Do i require technical team ?
2. how do we upload open sales orders, customer master data ?
please provide information
Data migration can be done as mentioned by Prasanth either through LSMW, or through BDC.
Just to add a little more into it, that in case of BDC you might require ABAPer to write a program or i say customized program which will cater to your needs during data migration, like what sort of data are you looking at, and how it will be transfered from one server to another server.
