[Help] System Disk Configuration with 1 System Disk

[Gremlin]

If you can rebuild md9 with one drive, why not with 2?

Is the flow for this process then, install my 2 new NVME drives and create a volume in RAID 1 configuration. Then proceed to migrate the System Disk from HDD1 over to SSD1.

The final part is where Im a bit confused, do I basically do another migration to the second SSD? or how do I make both SSDs the system disk at that point.

First, migrate the system from the HDD to one of the SSDs, then add the other SSD to the system drive as well.

That was said before, but I don't see it happening in practice. Please explain the process in more detail. The only method I see to progress from one system disk to two, is to re-install the system from a '.ins' file and HOPE the versions don't conflict when there is no '.ins' file for the version in place.
I actually did this today. Tos7.0.1105 in place and .ins for 7.0.0791 installed - Then updated back to .1105.
Incidentally, I also tried re-installing system configuration and that did not repair the network settings, despite that option being available and checked. A lot of trouble for what should be (conceivably) a simple operation.

Assume there are currently two HDDs and two SSDs, namely HDD1, HDD2, SSD1 and SSD2, and the system residing on the HDDs is to be migrated to the SSD.

1.Use the System Disk Migration feature to migrate the system stored on HDD1 and HDD2 to SSD1.
2.Use the Add System Disk feature to add SSD2 to the system disk as well.

OK - mea culpa - my only excuse was not seeing that button as active (old man's eyes and colour choices I guess).
Quick Follow up:
Why ask for a password when migrating disks, but not when adding? Not a problem for me, but a little odd.
Should one be able to access System Disk Migration from Tnas-mobile?

Adding a system drive has limited impact on the current system. However, migration and deletion operations are more sensitive and carry certain risks.
Although, under normal circumstances, migrating or deleting a system drive does not affect system integrity, both operations include a step that removes the system from the old drive — superuser(administrator) should be fully aware of this behavior.
Whether performing a migration or a deletion, please ensure that the target drive (for migration) or the remaining system drive (for deletion) is healthy before proceeding, to avoid system abnormalities after the operation.
