Migrate from 4 bay to 6 bay?

[Enquiries]

Hello,

Where could I find information regarding the following situation?
I am planning to change my qnap from TV453A to TVS673e.
Currently, I have raid 10 on 4x10tb HDs. I want to transfer the existing hard drives (10tb-10tb-10tb-10tb) to the new nas and have the following set up on Raid 10 (adding only 2 new 4tb hard drives)
10tb-10tb-4tb-10tb-10tb-4tb

I hope that I gave you a clear idea of what I am trying to achieve.

Please advise

Sincerely
Spyridon Iliadis

You can not create a RAID10 with mixed-size drives. You can move your existing RAID to a new NAS and add another 2x10TB. Or you can create a separate RAID besides the original one with 2x4TB as a RAID1.I hope this helps.
