Yeah, it’s all about the migration. I know it’s technically possible to do it by cloning the drive and copying over the channel data, but it’s kind of a scary prospect at the moment given the number of channels and the risk of force closures.
I’ve asked nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct if they had planned to release a standalone migration assistant for custom-built nodes but I haven’t heard of anything being planned or released yet.
