As someone who has migrated data to new PCs many times, I will say you should always back everything up and sort through it later. I have had many occasions where I’ve forgotten about important files or documents and deleted them because I didn’t know they were in the location I deleted. Storage is relatively cheap, buy a 30$ hard drive dock and a couple TB hard drive (spinning HDD, not an SSD), and use a program like FoxClone to completely clone your current OS drive. Then you can happily wipe it and still have the backup should you need it.
Michael’s clickbait game is amazing lmao
