I migrated mine a little while ago to play with my kids on their ipads.
The thing I am working toward is getting a local server setup so we have a persistent world we can build on.
I'm about to jiggle everyhting around on work servers, but after that I'm mor than happy to host a vm for you as a minecraft server
I have a new NAS and I did have docker running and it was OK when I tested it but soon as the boys started building crazy stuff it kept crashing. Even despite the min server specs I think you need 16GB for a start and at least 4 cores for the CPU and better to be 8.
I am keeping my out for a mini PC of sorts second hand to run windows and docker. I have a mac mini but its like 2019. Does the plex and torent and Apple music side fine, just too old OS to run Docker.
