Lucky me, I guess.

Is there a way I can install TOS 6?
F4-423
TOS version is 6.0.694
BIOS is 5.19
Hard drives 4x ST24000NT002-3N1101 24TB Iron Wolf Pro
TOS - Crucial P310 4TB PCIe Gen4 2280 NVMe M.2
Hypercache - Crucial P310 4TB PCIe Gen4 2280 NVMe M.2
OWC 32GB (2x16GB) DDR4 3200 PC4-25600 CL22

Since 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.
Sorry, this actually worked.

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.

Re storage pools - are they associated with Volumes? Plus - where are the 'home' folders and where are your apps installed?
{In my case with fresh install I use the nvme Pool for Volume1 with user Home folders and app installation.}
If the Storage Pool is unused there should be no issue with deleting it.

F2-424 TOS7.0.1278 - 2x500GB nvme (P3) Traid, 2x6TB HDD (HGST) Traid
F2-221 TOS7.0.1278 - 1x3TB Ext4, 1x4TB Btrfs
F2-425+ TOS7.0.1278 - 2x500GB nvme (P3) Traid, 2x6TB HDD (EXOS) Traid

Storage Pool 1 / Volume 1 = NVMe
Storage Pool 2 / Volume 2 = Hard Drives
Desktop, #recycle folders are on Volume 1

I am assuming all apps are on the NVMe, since I did all the updating possible before adding any hard drives.

Are you saying I should delete Volume 1? Where do I do that? Storage Manager > Volume? Or Storage Manager > Storage Pool?

Ideally, I want to have Volume 1 / Storage Pool 1 on the hard drives. And no storage / volume on the NVMe at all.

EDIT:

Never mind. I went ahead and deleted Volume 1 / Storage Pool 1

I get nervous when I see 'Delete', and I get overcautious.

Thank you for all the help.
