What is the difference between the 'Break Mirror' vs the 'Remove Mirror' option?
The "Break Mirror" operation, will stop the mirroring on the selected volume, without affecting the data on any disk. (Data will remain untouched on both disks).
The "Remove Mirror" operation, will stop the mirroring on the selected volume and destroys all the data on the mirror disk. (Data will remain only on one disk).

Thanks for the information.
Upgrading to Windows10 Pro keeps failing. I hope this clears the path for a successful upgrade.
Is it possible to "re-establish" the mirror once the upgrade has been completed?
