Transfer Assets from one asset class to another

Hi All,

I want to transfer all the assets from a specific asset class to a new one. I know I can do it through ABUMN. but I want to transfer it on the date on which assets were capitalised initially. As all the assets have different capitalization dates, it is not possible to create BDC. and data is huge, so manually doing it also not a wise decision. Can you please tell me how would I do it?

Thanks,
