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
