Lucky me, I guess.
Is there a way I can install TOS 6?

Sorry, this actually worked.MikeZhang wrote: ↑02 Sep 2026, 06:02Since the new NVMe SSD is now the system disk, we recommend removing the old system partitions from the previous system disks. This does not require formatting the hard drives or deleting the existing data.
Please follow these steps:
1. Power off the TNAS and remove the existing hard drives.
2. Leave only the new NVMe SSD installed and boot the TNAS normally.
3. After successfully entering TOS, insert the original hard drives while TOS is running.
4. Wait until TOS detects the hard drives and confirms that the existing data/storage pools are accessible.
Go to: Storage Management → Disks → System Disk
In the System Disk list, identify the non-current/old system disks that still contain the previous TOS system.
Select the old system disk(s) and choose Delete/Remove to remove the old system partition.
Important: Please make sure you select the old system disk/system partition, not the storage pool or data volume. Do not select “Erase Disk,” “Delete Storage Pool,” or format the hard drives.
After the old system partitions have been removed, reboot the TNAS with the NVMe SSD and the hard drives installed.
The purpose of this operation is to make the new NVMe the only active TOS system disk, while keeping the existing data on the hard drives intact.
Please also make sure that the NVMe SSD is selected as the first boot device in the BIOS/UEFI.
I got confused, but eventually figured it out. I didn't realize this 'System Disk" meant a tab, and I also didn't realize I had to use the trash can icon.
I was able to reboot without issues.
My one remaining issue is that I now have two Storage Pools. One on the NVMe (Storage Pool 1) and one on the hard drives (Storage Pool 2). How can I change this to have only Storage Pool 1 on the hard drives, and no Storage Pool on the NVMe?
Thanks for the help.
