Migrate from TrueNAS core to scale, I have a question!!

Hello everybody!!

I am still new to self hosting and such but I’ve been running my TrueNAS core PC with a NAS HDD and 128gb ssd a cache etc for the last few years. Just using it as basic storage and media serving via Plex. I also hosted a Minecraft server for a while too, however, that was difficult especially with the crappy MineOS and or hosting it in a jail sucked. Didn’t want to virtualize honestly. Not super big into virtual servers as of right now, but may change in the future.

My question: I’m wondering what the best method or guide would be to migrate to TrueNAS scale from Core without any data loss. I’ve read it’s possible but I’m not entirely clear or sure how. So I wanted to ask here and see if anybody had tips, direction, guides or any advice or help to help me know where to look or how to do it properly and safely. Thank you!!
