Transfer Leasing contract from insolventer GmbH

Hello together, Have a question about leasing. Company A is insolvent and the leasing contract is to be transferred from company A to company B. Both have the GmbH as legal form. The problem: Company A has done the business so far and company B has been inactive so far, but has a neutral balance sheet. The whole goes over the VW leasing company. The shareholder/GF of both companies is the same person. My question(s): What is the transfer in the way? Company B must have certain sales/revenues u What credit quality result can be expected from such an inactive company (B) and how will the Leasin company react to the transfer? Thank you for your help! Greetings, Thomas
