Auddis migration inactivating Direct Debit accounts

Hi

Any advice on the pitfalls/process of migration to Auddis would be appreciated, but specifically we are trying to work out how we identify unused Direct Debit accounts that need to be inactivated. Unfortunately old bank account details for Direct Debit accounts have never inactivated in the transactions tab, credit card radio button when new details have been received. When we migrate we must only take over live accounts.

Thanks
