Brand registry – updating old listings to my new registered brand

I just finally signed up to brand registry. I would now like to convert all my old listings (around 10 years worth) to my new brand name.

However my brand name is not the same as my business name (due to a trademark issue I have had to add ‘trading’ to the end of my business name to get the brand name).

So my business name is XX, but my registered brand is XX trading.

I have a mixture of listings, some of which are under my business name (XX), some of which under generic.

What I really need to know is, is it possible to have these listings changed? If it is possible, can anyone direct me with the correct route to do this.

Thanks so much for any advice.

Side note, I only sell on Amazon UK.
