I wish i was dilligent enough to do that. Generally, for migration, I use a new hdd for the OS, and mount my previous drive as a documents drive. I also get a separate drive for a full backup. I’ve been doing this for so long that I have uninterrupted personal files since 1997. However, it requires a good cleanup and organisation of all documents since the previous migration, and I’m too lazy to do it until I’m forced to.
