I want to have a private nostr relay, where do I go?

I want to migrate data from existing relays to that new relay. How do I do that? Are there already ready solutions, so I don't need to code it myself?

On top of my private relay, I want to have a website / UI, so I can easily search through my messages. Like browsing some blog posts.

It is a long post, but all those are related to me.

Thank you in advance for suggestions.
