Old NAS broken in only 5 years. New NAS setup a nightmare when you don't know the QNAP software.. Hints?

Bought two bay TS-x35 in 2019 In 2025 everytime problems and interface extremely slow not loading. Only use of this NAS is surveillance…

Bought TS-264 moved old hard drive and a new one into it and it came to life…Very quick interfacing etc. but no longer any IP camera’s or QVR pro and invalid licenses while it was sold with specs for 8 camera’s Had two extra licenses on the old one thus 6 cameras. But no video, no liceses no QVR pro.

Move old nas to new nas online was presented as just moving the harddrives… Well now what? How do I get this working again? Buying new QVR pro license? That cannot be true after only 5 years working of old NAS.

Any advice highly appreciated

So it was a two bay NAS..why was there a new and an old disk? How were the disks setup?

For licensing questions, best to open a ticket with QNAP

Well I took one old drive from the old NAS and one new drive as I wanted a new two bay nas and new drives to be sure for the coming years. But the old NAS was so crippled that I could not even do that copying process on the old NAS. This part of the process on the new NAS went well. It booted up like the old NAS but reacting well and I was able to rebuild the raid with the new harddrive during one night. Than I took the old harddrive out and replaced also that one with a new disk and rebuild the raid again. Thus now it’s a new NAS with NEW drives with the same IP address and same login etc… BUT absolutely nothing “good” transfered from the old NAS to the NEW NAS when it comes to surveillance. Only two invalid licenses are visible and none of the camera IP addresses etc as the whole surveillance app wasn’t even installed anymore??? How did that kind of information not come with the old drives to the NEW NAS? QNAP states online that moving from Old NAS to New is simply putting in the old drives into the new NAS well that only is true very partially..

Any licenses are bound to the NAS itself and not to the disks, hence the need to open a ticket.

Okay thank you so I need to open a ticket and see how QNAP resolves our case. Thanks I’ll try that

But than still, Why is my camera information gone? Do I really need to try boot up the old NAS and somehow very slowly copy that information from there? or is it somewhere on the harddrives and the new nas should read that information somehow?

As there is no TS-235 (Do you mean, TS-231.. or TS-253?), they could run on very different firmware and/or processor platforms. QNAP also just released yet another version for new platforms, so this is all a bit dynamic right now.

So include this request/question in the ticket as well.

QNAP in all their wisdom stores some information in databases that you have to export from each app. For example, take NotesStation. If you backup your NAS and then wipe it but have notes in NoteStation, they are gone unless you previously went in and exported/backed-up your notes.

In the surveillance apps, you have to export your cameras and then import them in the New NAS. And your video recorders are on their own storage spaces so you would’ve had to make sure you backup those storage spaces as well.

Yes sorry TS 253 indeed

Sorry but that doesn’t make sense to me yet due to lack of knowledge on this. The old NAS was detoriating since early 2025 becoming really slow. It started with some of the 6 video feeds not coming to the windows 10 desktop and QVR pro connecting very poorly to the NAS. I made sure the old NAS was running the latest QTS version.. had to wait minutes to get through those screens while connected to the network for updates. Updated all the apps, but nothing made the NAS workable anymore. Even taking the nas disconnected from network and do direct connection laptop to NAS than ping speed fine, but Webaccess extremely slow. However the harddrives and memory and CPU usage were all reporting OK status in the NAS. But IO-wait times found through ssh login were up to 600ms.. Thus I suspected bad drives (somehow broken IO) although the NAS said both drives OK. Taking one drive out than back in after a few minutes the NAS reported rebuild time more than 12 days!!! while not even connected to a network. At this point I bought a new NAS and two new drives and read about the 3 ways on QNAP website to move from OLD NAS to NEW NAS… And went for option 1. Old drive into new NAS

Surprisingly the NEW NAS booted fine on the old Harddrive number1. Harddrive 2 I did not touch or reinsert again as I did not finish waiting 12 days rebuild time in the old NAS. Instead as the new NAS booted fine on old harddrive 1 (8TB) I than inserted also an 8TB new harddrive as I was still thinking that either 1 or 2 of the old drives were extremely slow. But Old harddrive1 to new harddrive took only 9 hours to rebuild the raid. So that should give me a perfect copy and working NAS like before?. After this step I reconnected it to the network and than found that no camera’s were automatically recognized even worse the QVR PRO app was no longer installed??? Apparently the NAS software is not running from the harddrives? or the hardware is so different that the old harddrive was used to startup but in a ¨slimmed down” mode?

Now at this point your comment might come into play… But I don’t understand. I did exactly what QNAP suggests on their website and got a very crippled new NAS. Ah the new nas finds my 6 camera’s but with the info I wrote down from 2019 none of the camera’s give an image… Thus I might still reinsert Hardrive 1 into the old NAS and boot it up again without connection to the network and see if I will find the missing information.

Sorry for the long story but now its at least documented what my process was in the last two weeks…

OK. I see what you are saying now. First of all, I don’t know how many drives/storage groups you had installed in the original NAS. If QVR Pro was installed in a storage group that doesn’t exist in the New NAS, it would not show up.

It’s also possible that the hardware was different enough from old to new that you had to reinstall QVR Pro. I’m not entirely certain why your cameras and all were not there. But it’s never a bad idea to back up your cameras and then you can always restore them if they are not showing up on the New NAS.

It might be best to open a support ticket.

Hi @AVB I checked your support ticket and this post, and I think there might be something wrong with your operation step, causing the data to be out of sync.

I did not found which RAID type you used on your old 253 NAS (btw, 253 Pro? 253A?) but since you say the RAID has been rebuild, I guess it should be RAID 1?

The latest version of 253A and 264 is QTS 5.2.7, we assume you confirmed firmware consistency before migrating.

But you only use one old HDD on the new NAS, instead of both 2 old HDDs, this might creating a new RAID instead of restoring the original RAID, this might be the reason why your settings have all disappeared.


The license issue has already been answered by others, and it is basically based on the device, but we can assist with the license migration.
