Hi,

most of the points already mentioned are absolutely correct.

To add some more details:

• You do not have to export the data into flat files as Vikrant told above. But you can access the data directly via LSMW coding where you select the data from the database directly. Then you can also easily add some rules to exclude data records.
• You can perform the upload via Idoc. However especially for master data it is sufficient to add new company code information to the data record. For example you can use a simple batch recording to copy the company code data of a customer. This can be more efficient than using Idocs. 
• It could be necessary that you block the old master data records via mass update. This can also be easily done via migration.

Hope my addition is helpful.

For transactional data I cannot give general advises. The process is mostly more complex than for master data and depends from the object and environment.
