I have updated all of my workstation computers in my office to Windows 10 with very little problems. Now it's time to update the main computer. My main computer has dual HDD in a RAID 1 configuration. Can I pull one of those drives, and update to windows 10 on the remaining drive and make sure that there are no issues. If so, I would reformat the remaining drive and replace it and allow the computer to restore that drive. If not, I can swap the Windows 10 drive with the Windows 7 drive that I pulled and resume use of the computer until I can plan for an appropriate upgrade? Thoughts? Thanks in advance for your input.
