Hi, 

I try installed an app on odoo8 on odoo9 but the app require the multi-company module and when i install multi-company module, i have the error saying that model multi_company.default not found. I can see that in odoo8, we actually have that model in res_company.py but that model not exist in odoo9.

Can anyone have any idea about multi company in odoo 9? Why the model has been delete or move to somewhere ?
