That leads me to my next question...
What to back-up, save and the order of which to do things?
Here was my plan:
1. Use new 2TB external drive to back up everything from current Win7 system SSD and Data HDD.
2. Take particular note of any controller assignments, profiles etc, especially in DCS and CLOD.
3. Update Bios
4. Remove existing Win7 SSD (keep in safe place just in case)
5. Replace with new SSD and install Win10
6. Establish link to Data HDD for User data etc.
7. Install all games to new SSD copying what I can across from back-up made at point 1.
8. Fliegen!
Have I missed anything?
Is there anything you guys would do differently?
