Employee purchasing the business. What happens to our account?

I am the only employee for a small business and I am in talks to purchase our company as the owners wish to retire.

We currently sell on Amazon, both FBM and FBA.

The name of the company would stay the same, but the LLC would change from a partnership (the husband and wife who are looking to retire) to just myself and I know this would generate a new EIN number and change the name associated with the business.

The address of the business would also change, though it would still be within the same state.

Is it possible to keep the existing Amazon account, or would I have to start over?
