Data Migration for Business object -"BusinessPartnerSolutionExtension" extension fields

Hello Experts,

I have created extension fields in BusinessPartnerSolutionExtension xbo. Due to solution design - I need to have these extension field in this BO instead of Customer BO.I need to migrate the data for these extension fields.

I have tried creating odata extension for this XBO- but odata is not available. Also, I cannot find this BO in data workbench. Is there any way to migrate the data in the extension fields added in BusinessPartnerSolutionExtension XBO?

Thanks,

Gayatri
