International tax and FEMA compliance

A foreign company (F1) entered into an agreement with another foreign compan
y (F2). For this reason, the subsidiary of F1 Indian company (I1) has made a sale of certain assets/division to the foreign company F2. The consideration for the sale shall be paid by the F2 to the F1. F1 will then make the payment to I1.

So here I want to know the FEMA compliance required in this transaction as well as the tax implications of the same.
