How do I convert old BTT to new?

Could you please elaborate on the process of converting old BTT tokens to the new ones? I've heard about this recent update but I'm not entirely sure how to proceed. Is there a specific platform or exchange that facilitates this conversion? Also, are there any specific steps I need to follow to ensure a smooth transition? I'd appreciate any guidance you could provide to help me navigate this process. Thank you for your assistance in this matter.
