WDH2NC20000 from 1 TB to 2 TB?

I will need more space soon on my hard drive. Is it possible to change from 1 TB to 2 TB the two hard drives in my WDH2NC20000?
Thank you.

Some advanced Users have been able to swap the drives, however, it requires advanced SSH knowledge in order to migrate the unit’s OS. This procedure is not warranted or supported by Western Digital.
