Windows 10 decided to update a machine in a client’s office. The update took 4 hours and the employee could do zero during that time. A few weeks later a Win 10 machine at the same office crashed and would not start. I was left googling error codes from the BSOD. Nothing worked and I had to reinstall. I decided I needed to get my own work stack off of windows. I installed Kubuntu. 2 years later and I like KDE, I like the Debian base, I hate snap, but mostly I’m working and productive.

7 hard drives at 12TB each in your luggage?

I did this same move two years ago. Make a list of critical must have functions. Get a second storage drive like your current one, swap out the old and install Kubuntu. Get those critical apps installed and tested. Create a virtual machine out of your old primary drive. Boot that inside Linux when needed.

This is exactly what I did. Later I copied my old system to a VM and I boot it up inside Linux when needed.
