How to convert AR Receipts in Fusion Cloud?

Our client has a requirement to convert all the last one-year AR Receipts into Fusion. When we checked the ways to migrate bulk number of receipts, we noticed that there is no separate FBDI to load AR Receipts, the FBDI is only for Lockbox. Our client was not implementing lockbox and also it does not make any sense to use lockbox for migrating historical data.

We noticed there is ADFDI to load the AR Receipts, but we are not sure how efficient it is in terms of handling large volumes. I personally never seen this requirement of migrating AR Receipts into Fusion ever in past.
