Yes, you can take a hybrid approach, categorizing your product listings to support each platform and maximize your results. You can also transition products gradually and track results. But make sure you don't list a product on both platforms because once something is listed as "Sold By Amazon," it's very tough to compete with it and win the buy box. While you are not allowed to have more than one seller account, having both a Seller Central and a Vendor Central account is not against the rules. This allows you to take advantage of both platforms and the unique configurations required to scale your business as it grows. A word of caution about the hybrid approach: having multiple accounts (especially one linked to the Brand Registry) can often lead to confusion about which content takes precedence.
