Migrating employee sites in AP

Hi experts,

We are creating a new OU and need to migrate about 300+ employee suppliers and their Home sites from the old OU to a new OU.

Is there an api that can achieve this?

We know there is a setting under Payables Options to Automatically Create Employee as Supplier - but this only works when the employee creates their first expense report. Instead we want to upload the employee suppliers up-front in one batch, as we need to attach the bank accounts and change default currencies.

Can anyone suggest an automated way to migrate employee supplier sites from one OU to another?
