My question is simple, but I want to confirm I understood the process correctly:

 

Can I upgrade my 4TB HDDs to 12TB HDDs one by one each month, starting with the parity ones first (disable array, remove disk, replace disk, reassign disk, rebuild) ? Does it matter that the first month, one parity will be 4TB and the other 12TB ?

 

Thanks

Yes, no need to disable the disks, just remove and install new one, then select it from the drop-down box.

No.

I'd do the parity upgrade rebuild in maintenance mode just in case SHTF
