I’ve never had Twitter but it seems like it’s not worth it from the things I’ve seen and read. I would probably just make a post and say something like:

“I've decided to transition my updates and interactions to Primal for a few key reasons: the platform offers enhanced privacy and security features, the quality of community interactions is exceptional, Nostr's decentralized nature aligns with my values, and I have more control over my content and how it’s shared. I’ll be using X as a historical reference for past posts. Thank you for your support, and I look forward to connecting with you on Primal!”

Or something along those lines. 

 💜💜💜
