It’s simple. Go to Tachiyomi and create a backup. Then, in Mihon, during the first setup, it should give an option to restore backup. You can also resotre backup in Mihon settings, then go to extensions and (trust) the restored extensions.

It’s pretty much the same app at its core. So no need to change file names or formats. Everything should transfer.

I swear Microsoft is intentionally trying to drive me away to Linux. Tried everything you can imagine to stop my pc from waking up when I put to sleep or hibernation. Yet the best I can get is it always waking up first time and then properly sleeping after the second attempt. I’m only stopped because of VR and dumb Anti cheat in a few games.
