Out of fear that I will mess something up.
Compatability might be an issue too I dont know for sure.
If I knew everything would go fine and be working afterwards
and that I would be able to set up future updates on manual instead auto
I would do it.
The current plan is to get a new laptop get everything working there then upgrade old one.
Which windows should I get the new one with? 11 12? whats the freshest and best now?
It's not a problem if you mess up if you already have a backup seed phrase you can anytime recover your wallet with your seed backup.
But if you have important files that you want to save why not transfer them into an external hard disk if you don't have HDD then a USB drive?
Windows 10 would be enough since all new Electrum are running fine.
