 I have some questions.

Question 1: I don't know about Step 9

9.Transfer meta-data from Old-M-100 to New-M-100:

At this step, Please call into support to have an engineer assist to transfer the Meta-data. Once Metadata transfer is completed successfully continue with Step 10.

why need engineer assist to transfer the meta-data。

Can't I just unplug the hard disk from the old device and plug it into the new device?

Question 2: I don't know if raid has been done on old m-100. If not, raid has not been done

Onyxx@New-M-100> request system raid add A1 force no-format
'no-format' will be ignored for the second drive in the RAID Disk Pair. Do you want to continue? (y or n) y

Operation may take few minutes. Check 'show system raid detail' for status

Onyxx@New-M-100> request system raid add A2 force no-format
'no-format' will be ignored for the second drive in the RAID Disk Pair. Do you want to continue? (y or n) y

Operation may take few minutes. Check 'show system raid detail' for status

Does this affect the data in the hard disk

This screenshot shows whether a1 and a2 are raid or not？
