Some things to try:
Disable secure boot
Disable TPM 2.0
Disable CSM
 
 
 

I would just boot it up and see what ip is issued via DHCP.  After that, go to the router and assign it a static address.

Answer Yes
Think JBOD + 1 or 2 parity drives.  Each parity drive can support one drive failing.  Parity drive(s) need to be same or larger size than other drives in the array.  
 
With pools on the side, you can pretty much do anything you can think of.

Domains = VMs and Appdata = Containers.  They can be on different drives (ssd preferred ) You are able to move these files on your own.
Would take some notes on what you move around in case you need to move things back if it breaks.
 

Check Preserve Pool Slots. 
The array slots you need to assign manually (don't check) Basically use your image and assign all but disk 5 so it is left unassigned.
 
 

The pdf here says operating temps 0-70C.  Not sure if it covers your exact model.  Saw 70C on a few sites while looking for something that seems official.

The trick I couldn't figure out was how to set different temp notification limits for different type drives... Hdd vs nvme vs SSD.
 

Consider after swapping parity and 1 data drive, see if all your data fits on the single drive.  If it does, remove all the excess old drives so you only have 1 data + 2 parity.  Then add all the new drives at once. Could keep things down to 4 parity rebuilds that way... If the data all fits on one drive anyway.  May need to do it with 2 if not all fits.
 
Edit:. Might be able to save another rebuild if you drop to a single parity instead of 2, I'm not certain that a final rebuild for 1 parity + all remaining data disks would work like I think.

Create the new share 'Media'
Use a file manager, I like the simplicity of Dolphin (now deprecated)
open up your split window and cut/paste from your original locations '/tv' to '/Media/tv'
 
Super important to use Cut, not Copy.  Provided you do not limit which disks are used in the creation of the share, the paste should be super fast as entire files are not being moved, only header information is changed.
 
Give it a test on a few large files.
 

Some would use the SSD as a cache drive.  What you have will not break anything though.

Hello Unraid Community.  This is my first post here and I found a solution for a problem I had all day and I wanted to share because I was unable to find this exact problem listed with a solution provided.  It is entirely possible that I have posted this in the wrong place, mods please feel free to put this where it belongs if so.
 
The Problem:
  Loading Unraid on a 64GB (and presumably larger) thumb drive.
 
The Solution:
1.       Run Unraid USB Flash Creator. 
         This works as an initial install or as a restore from a backup .zip
2.       When it hangs at ‘Syncing File System…’
3.       Run Rufus and use following settings:
Boot Selection = FreeDOS
Volume Label = UNRAID
File System = Large FAT32
4.       START (Run Ruufus) > OK.
Unraid Flash Creator should finish extracting/installing.
Eject USB
Install in Unraid device.
 
Incidentally, if the problem (which I saw a few threads on) is that the Unraid Flash Creator is hung up on 'Syncing File Systems', the alternative to Rufus is to run a Windows Quick Format naming the volume 'UNRAID'.  When it completes, the Unraid Flash Creator continues its process of building the flash stick.
 
Thank you all for being such a helpful group.
