Add-on upgrade to SAP Business One 9.1

Hi,

Our customer wants to upgrade their SAP Business One to 9.1 from 8.82.

We created an add-on to support his business requirements using B1DE for 8.82.

Is there any B1DE version for 9.1?

If not, Can we compile this add-on directly in B1 Studio?

If not, Is there any conversion tool available?

Or

We need to do it from scratch using B1 Studio which need considerable time 😔

Request more information from community on this

Regards

Ajith
