Logseq to Obsidian.
Logseq’s markdown is weird and not standard. Everything is indented and in a list, even headings. I love me some open source, but this is a hard no.
Open your logseq files in a plain text editor and compare with the standard. I spend much of my time editing them back to Markdown.
Syncing logseq is easy on Syncthing. The only issue being that one has to watch out for conflicts by not editing one on one instance before the other sends it/it is received, but that’s a sync issue not Logseq.
I’d suggest no-one ever dual-boot Windows with anything. There are to many mishaps when Windows takes it into their head to fuck the bootloader.
Put the OS into a VM. If you only use Windows for one app put Windows into the VM. Otherwise put Linux into the VM until you find you’re mostly using Linux.
Unless you have an old PC laying around …
