In order to gain access to Brand Registry via IP Accelerator, I'm in the process of applying for an "intent to use" trademark application with a new brand logo and brand name that's 1-word less than my current listings (Currently, Blue Water Wipes - Updated version is "BlueWater"). The products that I will be selling are the same, but we've updated our logo/brand name so the pending trademarks will be for the new logo designs. My products with the new logo/design are currently being manufactured and will be shipped within the next month which is why I'm submitting an "intent to use" application. I only have 1 product in different variations under 1 account/name. I understand that there are no legal questions so my questions will be Amazon-based. My questions are;

Since I'm submitting this as an "intent to use" application because my new designed products are being manufactured, will I still be required to submit an image of the products(as one of the required steps in the Brand Registry)? The other question is, after I register for the Brand Registry, what happens to my current listings with my current logo/design? Since I'm the owner of the brand and the products, can I sell them under the Brand Registry with my updated Brand name and logo/design? Again, my product is the same. We've updated our brand name to 1 less word than its original with the same products.
