There’s no reason to hope that you can change to a new operating system and you can copy paste exactly what you did in the other, completely different operating system. However that doesn’t mean its hard. There are distros that make it really easy to transition too. I had a really easy moving over, but I was fine with adapting to new workflows and software and OS.
I run Linux while having 3 kids, my fiancee, a full time job that has a lot of OT, family health issues I have to support etc. Life is always busy and will always be busy. I pace myself with what I want to learn based on how busy my life is at that time. Not pacing I would burn out. I advise the same.
I also think being pissed off at Microsoft isn’t enough to get into Linux for the long term. Its enough to just start. You need to be able to want to learn something new because if you make the switch, run into an issue with some distro, can’t get past it, you’ll end up right back where you left off.
Best of luck either way. Definitely do your research first and follow good rules for backing up your data.
My dot files stay with me. I’ve never been into sharing my dot files. Privacy and I’d rather help someone do something similar if they are interested instead of sharing a dot file.
