Migrating Domain Environment When Replacing NAS

I purchased the TS-431P in November 2017 and have been using it with RAID6. The current version is QTS 5.2.10.3577.

Recently, the HDDs in Slot 3 and Slot 4 often suddenly become unrecognized, so I’m thinking about replacing it. I’m considering switching to either the TS-233 or TS-216G, but I’d like to know about migrating the domain environment I have set up on this NAS at home.

Both of these products are said to be able to serve as domain controllers, but how can I migrate from the existing NAS domain environment?

There are two users and about seven PCs participating in my home domain.

Both of these two models can be used as domain controllers. If you confirm that normal system migration is possible between your two models, the settings will be carried over as is.

I tried reading the TS233 User Guide.

On p.51, “Status and Setting Changes after NAS Migration,” it says:

Windows AD configuration: Windows AD configurations must be reconfigured.

From this, I couldn’t read it as if settings could be carried over.

Is it really possible to carry them over?

Are you planning to move the existing hard disk as it is, or will you be using a new hard disk? If you move the existing hard disk as is, the domain controller settings should also be transferred as they were.

Could you please confirm your situation? After that, I will check internally. Thank you very much.

Right now, I’m using a TS-431P with 4 slots in RAID 6.
The next product I’m considering buying has only 2 slots.
When migrating, is it possible to take the HDDs out of the old device and put them into the new one to transfer the data?
