Drastically Renaming a Product Title which has reputation

Drastically Renaming a Product on Amazon

In a state where we may be renaming some of our key products to extremely different Product Names as a so called “rebrand” compared to what they currently are. We have years of feedback built up on Amazon around the specific product names as it is technically a brand name. What are the implications of changing the Title of our Amazon Listing drastically and all feedback on the product underneath etc… showing the old product name. Would this look deceiving? People wont put 2 and 2 together when they see 4 years of feedback woth a different product title compared to the new product title. Does this then have implications with Amazon taking our priducts down as they look false when in reality it is the same product with a new Brand Name type scenario. Any advice is appreciated.
