How do I transfer from SPS to Splinterlands?

I'm curious about the process of transferring my assets from SPS to Splinterlands. Could you please explain the steps I need to take in order to complete this transfer? Is there a specific platform or tool that I should use? Additionally, are there any fees associated with this transfer, and if so, what are they? I'd appreciate any guidance you can provide to help me navigate this process smoothly.
