Migration of Business Component from PI 7.1 to PO

dear experts,

I am working on migration project from PI 7.1 to PO .

I am using migration tool to Move the Configuration Objects from 7.1 to PO.

those Objects in the SLD i.e Business System , I imported from the SLD but with regards to Business Component do we have any other menthod ...?

Because when i migrate using the migration tool Only Business Component is not migrating its giving me error when activating the objects in PO.

i did try to just do file transport for that one Business Component & import tht in PO from cleint system its also not getting picked in the Integrated Configuration.

thanks
